There are three explanations:

1. As we all know, the product of two factors, one of which finds the other factor, means the other factor:

2. A number contains several other factors.

3. Quotient is the number of division operations.

As follows: 7/4,7 has at most one 4 and is greater than 3, so this quotient is 1 and the remainder is 3;

There are at most three 3s in 9/3 and 9, and there is no redundancy, so this quotient is 3 and the remainder is 0;

Then, the quotient of A divided by B indicates how many Bs can exist in A at most, which is the quotient.
