# Perl 5, 42 bytes

40 bytes plus two for the -lF flags (-M5.01 is free): perl -lF -M5.01 script.pl

/#+/;map{unshift@F,pop@F}1.."$$'";say@F


Explanation:

• -lF reads the input, removes the trailing newline, splits up the remainder into characters, and puts that split into the array @F.
• /#+/ finds #s in the input string and sets $ equal to the stuff before it and $' equal to the stuff after it. "$'$" is thus the number of times to rotate the array.
• Now comes a loop: We increment $i (which starts at 0) and test against "$'$" (the number of times to rotate); if we haven't reached "$'\$" yet, we redo the loop. What does the loop do? Simple: it rotates the array (pops the last element and unshift`s it onto the beginning).
• After the loop exits, we print all the elements of the rotated array.
