i need to know how to divid intergers fast its just ben so long
use a cheap calculator?

you know, sometime they make promotion when you buy something like cheap printer, they even give you solar power calculator for free. and those calculator can do anything with integer, but for divide operation, it will display the result in floating point most of the time. you have to manually truncate it to integer. usually it's easy enough just by looking at the result and you can do it mentally in less than a second.

You say fast ............... how fast? How large are the integers you want to divide?

How much accuracy do you need? If you don't need a lot of accuracy, you can get an approximate answer using rounding and simple logarithms.

For example what is 9853 divided by 64?

Well this can be expressed as 9.853 X 10 exp3 divided by 6.4 X 10 exp1. So round 9.853 to 10 and round 6.4 to 7. This simplifies to 10/7 X 100 or about 1.5 X 100 or 150.
