How does division work?

[comphappy]

If you need the extra places the most efficient way to do it will be to bit shift the dividend, and remember that any time you need to do a calculation, you need to bit shift the result back. using bit shift instead of multiplying by something like 10 will save you a few clock cycles.

multiplication 8-bit by 8-bit method (if you multiply by an arbitrary value such as 10)
see here http://www.dcc.unicamp.br/~celio/mc4...los/mul8x8.asm

Program Memory : 14 locations
# of cycles : 71
RAM : 5 locations
That is a really big waist

bit shift method
c equivalent
x<<1;

can be done with the single asm command lrol (load and rotate left)
