Personally, I try to avoid any form of division (other than ^2 shifts,) 
when working with low-end micros. I see these as "expensive" operations 
and try to keep to additions, shifts, and logical operations. (And 
multiplications, if the device happens to have a hardware multiplier. 
But not common on low-end devices.)
