This document describes a method for dividing any number by 9 using an algorithm based on adding adjacent digits. The method is demonstrated by dividing 120131 by 9. The leftmost digit is kept as is, then each following digit is added to the previous sum. This continues until the last digit, whose sum is the remainder. The series of sums from left to right is the quotient, so for 120131/9 the quotient is 13347 and remainder is 8. The author promises to explain carrying in future examples.
