Dividing Decimals by Powers of Ten (Part 1)

The video tutorial explains how to divide decimal numbers by powers of 10. It begins with an introduction to the concept, followed by a detailed example of dividing 12.5 by 10. The process involves dividing both the whole number and decimal parts separately, then combining the results. The tutorial emphasizes the movement of digits in the place value chart, illustrating how each digit shifts one place to the right when divided by 10. This is equivalent to moving the decimal point one place to the left.
