If 525 balls are dropped in jars such that each jar has 6 balls. How many balls will be remaining and how many jars will be filled?

To find the number of jars and number of remaining balls:
525 $÷$ 6

$$\begin{array}{c}87\\ 6525\\ -\underset{–}{48}2\\ 45\\ -\underset{–}{42}\\ 3\end{array}$$Thus,we have a quotient of 87 and a remainder of 3.
So, 87 jars would be filled and 3 balls will be remaining.
