Because otherwise you would only know how to subtract and add with the same integers. Not a particularly useful skill unless just those integers turned up!
When you can do addition and subtraction without recourse to it. Then it simply becomes a distraction.
Any fraction can go into any other fraction. The concept of "going into" for a limited set of numbers is useful only for integers.

The set of integers is divided into three subsets. One is the positive integers. Another is the negative integers. The last subset has one element -- zero. In sum, integers are composed of the positive integers, the negative integers, and zero.
The sum of all positive integers in infinite. I am not sure how this particular idea is useful.
It means they have no common factors. This term is really only useful for integers, preferably positive integers.
-- Integers are very useful when you need to count things. -- If you are running short of decimal points and fraction bars, then integers are definitely the best numbers to use, since they don't need any of those.

The answer depends on what you wish to DO. And since you have not bothered to share that bit of information, I cannot provide a more useful answer.
Yes, at least for integers: You see how often you can subtract a quantity. But I guess it is more useful to think of division as the inverse of multiplication.

Negative integers, zero and the positive integers, together form the set of integers.

Non-positive integers are zero and the negative integers.
The set of integers represents the integers.
