Understanding Division with Base 10 Blocks

This video tutorial explains the concept of division using base 10 blocks. It demonstrates how to divide 87 by 5 by modeling the number with rods and units, sharing them equally among five groups, and handling remainders. The process involves exchanging rods for units to facilitate equal distribution, ultimately showing that 87 divided by 5 equals 17 with a remainder of 2.
