I've tried to google this but all the answer goes to the same obvious answer; to divide c/b, you click on cell b, the divide and then cell b, taraaaaa. Well, as far as I know QUOTIENT function is used to divide numbers in Excel, but it only gives you whole numbers. So if I need to use it to perfom this calculation monthly, in which case I need something more ambivalent that c1/c2.....though I tried it after countif, but of course it didn't work. Any ideas I will be much appreciated
