For a simple problem like that one, you can use either long division or short division.
You can also get an answer quickly with a calculator, but that method has two
serious disadvantages:
-- You don't learn how to do it, so if you ever have to find an answer quickly
without a calculator, you're in big trouble. You feel awkward, and you appear
uneducated.
-- You don't learn how to do it, so you have no clue or feeling for what the answer
should be. You're willing to accept anything you see on the calculator, and if you
ever enter the problem into it incorrectly, you blindly accept the answer, which is
wrong, because you don't know any better.

Well, isn't that a happy little math problem we have here? If we want to find out what times seven equals 112, we can simply divide 112 by 7. And when we do that, we see that the answer is 16! Isn't that just fantastic? Just remember, there are no mistakes in math, only happy little accidents.
To solve this, divide 112 into 784. n = 7
To find out how many times 21 goes into 112, you would perform division. Divide 112 by 21 to get the quotient. In this case, 112 ÷ 21 equals 5 with a remainder of 7. Therefore, 21 goes into 112 five times with a remainder of 7.
112/16 = 7
Simply divide 112 by 2.
