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!

The task

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!


Leaderboard

Here is a Stack Snippet to generate an overview of winners by language.

To make sure that your answer shows up, please start your answer with a headline, using the following Markdown template:

# 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 leaderboard snippet:

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

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

AutoHotkey assigns numbers 1-n as variable names for the incoming parameters. It causes some problems when you try to use those in functions because it thinks you mean the literal number 1 instead of the variable named 1. The best workaround I can find is to assign them to different variables.

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.
