1. A sample with 37621, sum the digits (19)

2. Subtract the sum from the original number (37621-19) to get 37602.

3. Sum the digits in the result (18), they will ALWAYS be a multiple of 9!

Tried this with up to 9 digits and it works every single time.

But what, if anything, can this be used for?
