When I was writing arm26 (i.e. arm2) assembly for the Archimedes everybody passed around a block of ASM that did division since the processor had a whole 16 instructions and integer division wasn't one of them. Things are less primitive these days but the memory still brings a smile to my face.

MIPS was also like that, if I remember correctly, division and multiplication were assembler macros.

  Reading about MIPS was where I first encountered the concept of a branch delay slot and I am -so- glad I've never had to write assembler for a processor with that feature.
