Explain how the position of the decimal point changes in a quotient as you divide by increasing powers of 10

Question

I'm doing a mid chapter checkpoint 

Answer 1

Dividing by ten shifts the decimal point of the DIVIDEND one place to the left, making that into a smaller number, the desired quotient, which is one tenth of the dividend.

 

Division by 10ⁿ shifts decimal point n places toward the left, similarly.
