Calculator Remainder Trick

Today, I'm going to show you how to use any calculator to find the remainder. Let's use an example. 678 divided by 37. First, divide.

Then hit equals.

Subtract the whole number and equals. The remainder is found in the decimal.

Then multiply by the divisor. The divisor is the number you are dividing by. Here, it is 37.

We can check this. The quotient is the answer to a division problem. It has a whole number part and a remainder. The remainder is the leftover. Take the whole number multiply by the divisor and then add the remainder. This should give us the dividend. The dividend is the number you are dividing. Here it is 678.

18*37+12=?

It does work. I get 678. And it will work, every time.
