Help!  I need a routine to divide two 32bit integers with a 32bit result
written in 68010 (or 68000) assembler [or even 'c' using no long divides :)].
The 68010 has only 16bit / 16bit --> 32bit integer divide instructions.

I would like my program to behave exactly as when run on a 68020 with full
32bit divide instructions.  This must be an extremely common routine...

Abstract algorithms, source code in asm or c, references, a dozen red roses,
any help would be most appreciated.
