I have developed a way to teach long division that enables kids to discover the steps of the algorithm and understand the underlying concepts while learning to perform the algorithm proficiently.

Therefore, the quotient is either 1 or 0. The division algorithm performs either an addition or subtraction based on the signs of the divisor and the partial remainder.

I previously dismissed long division as a meaningless math procedure. Am I backpedaling now in response to readers' comments?

For instance, he tells us the ARM processor used on the Raspberry Pi doesn’t have a divide instruction. Without hardware division you’re left to implement a binary division algorithm.
