Perhaps it's the decimal point that's putting you off? If you convert the money into cents, you won't have a decimal point to worry about. $52.70 is 5270 cents. You can divide by 17 using long division if you like. 3 17's are 51. Take that away from 52 and put 3 as the first number of the answer. 52-51=1. Bring down the next digit 7 and put it after 1 and you get 17. How many times does 17 go into 17? Just once, so the next number in the answer is 1. So far we have 31 in the answer. The next number brought down is zero, and 17 goes into this zero times and there are no more digits to bring down. Just put zero as the last number of the answer which now reads 310. That is 310 cents. In dollars that is $3.10.
