Division by a number is the same as multiplication by its reciprocal. That is, n / a = n * (1/a) and as you should know, (1/a) is the reciprocal of a.

Not sure about the first part of the question, but when doing long division, the partial answer is multiplied by the divisor to get a product, which then is subtracted from the dividend, to see how much is left over.

lets say that you're doing a division problem that looks just like a multiplication problem. lets say its 10 divided by 5 so 2x5 equals 10 so the missing number in the problem is 2 MORE TO COME

you can use it

Multiplication and division are opposites, therefore by multiplying/dividing, you can use the other one to check your answer. say 2x2=4. if you didnt know that for sure (which you should,) you could go like 4/2=2. that means they are related
