The following is an example that shows how to do Estimation Division for the problem 727 / 3. 1. First write the problem as shown. 2. Draw a line down the side. 3. Beginning with multiples of 10, estimate how many times 3 goes into 727 without going over. 4. Write the number of times that you multiply 3 to the side of the line down the right side of the problem. [Write in the 100.]   5. Multiply 3 X 100 and subtract that from 727.       6. Again beginning with multiples of 10, estimate how many times you can divide 427 by 3. 7. Multiply 3 X 100 and subtract that from 427. 8. Again beginning with multiples of 10, estimate how many times you can divide 127 by 3. 9. Multiply 3 X 40 and subtract that from 127. 10. Estimate how many times you can divide 7 by 3. 11. Multiply 3 X 2 and subtract that from 7. 12. Add all the numbers along the right side which should be 100,100,40 and 2. 13.Write that number down below the right side line. 14. Since there is still 1 remaining on the left side, your answer should be 242 with a remainder of 1.
