The method$3$ function accepts an int count value and returns the number of boxes this count would result

in $($and the number left over$).$ The number of boxes means the number of filled boxes. The number left

over means the remining count that does not make up a full box. For example, if a box holds $5$ items and

you have $13$ items $$ then you would have $2$ full boxes and $3$ items left over.
