Computers and pocket calculators can accurately perform divisions in a fraction 
of a second.  I know it is possible to perform simple division by repeated 
subtractions, but via this method you end up with a remainder, which is 
inaccurate in terms of decimal precision.  So... how do calculators and 
computers without floating point systems get an accurate decimal answer to a 
division calculation?
