50.20 and 50.1999... recurring.
Two decimals are equivalent only if everything from the decimal point to the last non-zero digit is the same in both of them. Additional zeros after that don't matter.
502 can be divided by 251 (that equals 2). However, 2 and 251 are the only [integer] numbers which multiply to give 502. It is possible to divide 502 by fractions but not by any other whole numbers. Sorry.
