Division and remainder

This challenge, while probably trivial in most "standard" languages, is addressed to those languages which are so esoteric, low-level, and/or difficult to use that are very rarely seen on this site. It should provide an interesting problem to solve, so this is your occasion to try that weird language you've read about!

Take two natural numbers a and b as input, and output two other numbers: the result of the integer division a/b, and the remainder of such division (a%b).

This is : shortest answer (in bytes), for each language, wins!

Input/Output

• 0<=a<=255, 1<=b<=255. Each of your inputs (and outputs too) will fit in a single byte.
• You may choose any format you like for both input and output, as long as the two numbers are clearly distinguishable (e.g. no printing the two results together without a delimiter)

Examples

a,b->division,remainder
5,7->0,5
5,1->5,0
18,4->4,2
255,25->10,5


Note: Builtins that return both the result of the division and the remainder are forbidden. At least show us how your language deals with applying two functions to the same arguments.

Note 2: As always, an explanation of how your code works is very welcome, even if it looks readable to you it may not be so for someone else!

The Catalogue

The Stack Snippet at the bottom of this post generates the catalogue from the answers a) as a list of shortest solution per language and b) as an overall leaderboard.

## Language Name, N bytes


where N is the size of your submission. If you improve your score, you can keep old scores in the headline, by striking them through. For instance:

## Ruby, <s>104</s> <s>101</s> 96 bytes


If there you want to include multiple numbers in your header (e.g. because your score is the sum of two files or you want to list interpreter flag penalties separately), make sure that the actual score is the last number in the header:

## Perl, 43 + 2 (-p flag) = 45 bytes


You can also make the language name a link which will then show up in the snippet:

## [><>](https://esolangs.org/wiki/Fish), 121 bytes

• Can I reverse the arguments, i.e. instead of providing a b providing b a instead? – Erik the Outgolfer Mar 27 '17 at 13:29
• @EriktheOutgolfer: You may choose any format you like for both input and output, as long as the two numbers are clearly distinguishable – Emigna Mar 27 '17 at 13:30
• @Emigna Yeah, I was not sure if reversing didn't make them indistinguishable though. – Erik the Outgolfer Mar 27 '17 at 13:32
• @EriktheOutgolfer if you know that they need to be reversed you have no problem in distinguishing them :) – Leo Mar 27 '17 at 13:45
• Unfortunately, the BF algorithm doesn't work if the divisor is 1. – mbomb007 Mar 27 '17 at 13:45

It is too insane to do this challenge with NO! which is why it's non-competing (not really, the language is too young to compete in the bloodthirsty arena known as PPCG)

NOOOOOOOOOOOO?NOOOOOOOOOOO

NOOOOO?                          Divide               by
yes!                             line 1 result
yess                                          line 2 result

noooo                                      line 4 result


A yes is used to denote a line number (number determined by number of ss) but the output command takes either numbers or line numbers as arguments and noo!nooo is shorter than yess!yesss

Triangular, 21 19 bÿtes

$\:A@$U.vS/p%_<%mp<


Prints the result of division, a newline, then the remainder. Formats into this triangle:

     $\ : A @$
U . v S
/ p % _ <
% m p < ÿ ÿ


ÿ is the no-op that is automaticallÿ inserted when there is no code to fill the smallest possible triangle.

Trÿ it online!

Explanation:

I don't know whÿ \ is the first character... Removed it and managed to save two bÿtes. Still don't know whÿ it was there in the first place. ಠ_ಠ

Directionals:

     .
\ .
. . .
. . v .
/ . . . <
. . . <


This is how the interpreter sees the code, without directionals:

$:$S_%pUA@pm%

• $: reads integer input to the stack and duplicates it. Stack contains input1 input1. • $S reads another input to the stack, then stashes it in memorÿ. Stack contains input1 input1 input2, and memorÿ contains input2.
• _ divides the top two stack values. Now the stack contains input1 input1/input2.
• % prints the top of stack as an integer.
• p pops the top of stack. Now the stack contains input1.
• U pulls memorÿ onto the stack. Now the stack contains input1 input2.
• A pushes 10 to the stack. Stack contains input1 input2 10.
• @ prints it as ASCII (newline).
• p pops it - stack contains input1 input2.
• m performs modulus on the top two stack values. Stack now contains input1%input2.
• % prints the top of stack as an integer.
• the IP then runs off the plaÿing field, and the program terminates.

Other than the creator, I think only I am actively using it. Therefore it is rarely seen on this site; in addition it is esoteric.

Takes 2 inputs separated with newlines.

((@@[/#1#0%#1#0)10)5


Simply a curried lambda that returns a list with both the division and modulus. I'm looking for a golfier way to do this, something that doesn't involve lambdas.

Be sure to do tK1000 beforehand to view list items in the output.

&{div(&1,&2),rem(&1,&2)}


Anonymous function which uses the capture operator and returns a tuple containing the results.

Full program with test cases (and yes, the . in the function call is required!):

f =
&{div(&1,&2),rem(&1,&2)}

# test cases:
IO.inspect f.(5,7)      # 0,5
IO.inspect f.(5,1)      # 5,0
IO.inspect f.(18,4)     # 4,2
IO.inspect f.(255,25)   # 10,5

Sinclair ZX80 16-bit Integer BASIC (4K ROM), ~152 BASIC bytes used (listing)

 1 LET R=0
2 PRINT "ENTER A NUMBER THEN DIVISOR"
3 INPUT Z
4 INPUT D
5 PRINT Z;"/";D;"=";
6 GO SUB 9
7 PRINT R;" REMAINDER ";Z
8 STOP
9 FOR I=1 TO 0
10 LET Z=Z-D
11 LET R=R+1
12 LET I=(Z>D)+(Z=D)
13 NEXT I
14 RETURN


Some notes:

Because the ZX80 (with the old ROM) can only handle 16-bit signed integer numbers, your range is -32768 to +32767 for your inputs. There is no native modulo function, nor does there seem to be a >= (if there is then I can't find it) - hence why this had to be split in line 12.

I haven't handled the division by zero in the program, but I guess that it entering 0 as your divisor will keep the sub-routine from line 9 in an infinite loop (as it should), except for the 16-bit integer range, so Z/0 should be Z r ∞.

The byte count is only an approximation for now.
