This is an interactive notebook entry we used about what to do when you are using long division, and you get a reminder. It shows (using color coded directions) how to add a decimal and zeros, and gives directions about how far to take it out. For our class scholars divide until the quotient ends, or they find a repeating decimal, or in the case of an irrational quotient, they hit 3 decimal places. This document would be very easy to edit for your own class needs.
