What is division?

The students wrote down their definitions for division.  They are as follows:
Sophie:  It is where you split the number and share equal groups.
Alexis:   It is like 16 divided by 2.
David:  It is taking something and splitting it into groups.
Alyssa:  It is like 16 divided by 2=8.
Treyvon: It is dividing into groups.
Emma:  It is 16 divided by 2. So you figure out to split it in to two groups like this:
00000000 1 group
00000000 Another group
How many in each group? It's 8.
Jack:  It is taking a number and dividing it into a certain amount of groups.
Jada;  It is 16 divided  by 2=8.  It would be 8 because you have 16 chips and divide them into 2 groups.
