how do i find the remainder of this equation 66,114 divided by 79
Just divide 66,114/79 =836, I dropped the fractional part.
Take this new number 836 and multiply it by 79=66,044. Now subtract this new number from the original number, which was 66,114 like this: 66,114 - 66,044=70, which is your remainder.
There are other ways of doing it but this is the simplest.
