This node brought to you by the Egyptian Division of Everything.
The process used to divide numbers by the scribes of the Ancient Egyptian culture was (naturally) very similar to their multiplication structure.
Let's take 13188 and divide it by 314, the oldschool Egyptian way
Step 1: Create a column (away from the left edge of your tablet) beginning with the divisor and doubling it each line thereafter. Stop when you have written down the largest number that is smaller than the dividend.
Step 2: Along the left side of your tablet (or your copy of notepad), write a 1 in the first row. Fill this column with doubles as you did for the other column in the previous step.
Step 3: (Thinking about the mathematical logic behind this step makes my head spin in awe). Mark off the rows whose values in the right column total the dividend. (the marked rows are shown in italics above).
Step 4: Total up the marked values from the left column (2+8+32) and you will see that the answer is 42.

One more vaguely interesting note: In both the multiplication and division methods illustrated in these two nodes, the bottom-most row is always
marked, unless you have made an error.
In the case of remainders, the Egyptians expressed them as unit fractions as detailed in the Egyptian mathematics
