Oh honey, repeated subtraction is just a fancy way of saying you keep taking away the same number until you can't anymore. It's like breaking up a big cookie into smaller pieces until you can't break it anymore. So, if you wanna solve a division problem using repeated subtraction, just keep subtracting the divisor from the dividend until you can't anymore. Easy peasy lemon squeezy!

say you had 42 divided by 7. 42-7=35, 35-7= 28, 28-7=21, 21-7=14, 14-7=7, 7-7=0
no remainder count up the times you added 1(42-7=35), 2(35-7=28), 3(28-7=21), 4(21-7=14), 5(14-7=7) , 6(7-7=0)
so 42 divided by 7 is 6.

It depends on the problem. An integer subtraction can be one number, take away another number.
