58/7.......how many times does 7 go into 58 without going over....it goes in there 8 times....so 8 is ur whole number.....7 * 8 = 56....now take ur 58 and subtract 56 (58 - 56 = 2)....that is ur numerator, so basically, the remainder is ur numerator.....and the denominator, it stays the same.
so we end up with : 8 2/7
