The answer is 12 because 10 +2 is twelve
When you are dividing, sometimes the answer doesn't come out evenly. We call the part that's left over the remainder. 12 divided by 5 = 2, with 2 left over 12/5 = 2, Remainder 2

2 x 6 + 0 = 12 2 x 1 + 2 = 4 4 is not [divisible by] 8, so 60 is not divisible by 8. (The remainder when 60 is divided by 8 is 4). To test divisibility by 8: Add together the hundreds digit multiplied by 4, the tens digit multiplied by 2 and the units (ones) digit. If this sum is divisible by 8 so is the original number. (Otherwise the remainder of this sum divided by 8 is the remainder when the original number is divided by 8.) If you repeat this sum on the sum until a single digit remains, then if that digit is 8, the original number is divisible by 8 otherwise it gives the remainder when the original number is divided by 8 (except if the single digit is 9, in which case the remainder is 9 - 8 = 1).

2 + 10 = 12.
62 ÷ 12 = 5 with remainder 2
