Question

Trying to understand long division formula. 5 divided by 285.I have it down to 28-25 and i have 035 but why is 35 subtracted by 35 at the end ? Please explain where the 2nd 35 comes from.

Answer 1

Explanation:

At each step, the product of the quotient digit and the divisor is subtracted from the dividend. This gives you the new dividend.

When the quotient digit is 7, the product of 7 and 5 is subtracted from the dividend. The dividend at that point is 35, so you have 35 - 35 = 0. The 0 is the next dividend. Among other things, that tells you you're done. (Any additional quotient digits will be zero.)
