Hi,

I simply times the numbers with 10 or 100 - depending on the position of the decimal - and then divide it. For example, 625/2.5 = 6250/25 (after multiplying by 10) = 1250/5 = 250

The other method is simply doubling both numbers until you get rid of decimal and then divide it; but I find the above method more handy.
