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, 1, is kept the same. The next digit, 2, is added to 1, giving 3. Continuing to add each next digit, the running sum is 3, 3, 4, 7, 8. The last sum, 8, is the remainder, and the digits before it, 13347, are the quotient when 120131 is divided by 9. The author promises to explain how to handle carryover in future examples.
