Let’s put all the steps together to work one more problem. Next to the quotient of 17 write R18 for remainder of 18. This means the problem was done correctly and there is a remainder of 18. In this case, the divisor is 20, so 18 is less.
Check to make sure the 18, the answer you got when you subtracted, is less than the divisor. Bring down: There is nothing left to bring down. Subtract: Subtract the two numbers: 158-140= 18. Multiply: Multiply the new answer you have from dividing, which is 7, with the divisor 20. Write the 7 on the quotient line above the 8 and next to where you wrote the 1. Divide: how many times does 20 go into 158? The answer is 7 times. You will divide, multiply, subtract, and bring down. Now, you are going to do the long division steps again with a new problem: 158/20. Now, you have a new number 158 (which is also the new dividend. You are bringing it down and writing it next to the 15, which was the answer you got when you subtracted. In this example, the number you are bringing down is 8. This means you are bringing down the next number from the dividend that hasn’t been used yet in the first small division problem. The last step in the long division process is to bring down. You write this 20 underneath the 35 (which is the first part of the dividend, 358 from step one). In this example, you are multiplying 1 x 20, which equals 20. You are going to multiply your answer from step one and your divisor. So, you put a 1 above the 5 on the quotient line. The first problem you would work in this example is: How many times can you divide 20 into 35? The answer is 1. So, how many times will 20 go into 358? That is too large of a problem to undertake, and so you break up the division problem into smaller steps. The answer you write above the division symbol is called the quotient. Remember 20 in this problem is called the divisor, and 358 is the dividend.
HOW TO DO LONG DIVISION STEPS HOW TO
Continue reading to learn how to do long division problems! Step One: Divide If you can remember the four steps, you are half way to learning how to do one of these problems. Dad corresponds with divide mother corresponds with multiply, and so on. But isn’t it easier to remember: Dad, Mother, Sister, Brother or Does McDonalds Serve Burgers? Both of these phrases can help you remember the steps of a long division problem.
So, we do our DMS loop (division-multiplication-subtraction) until we use all the numbers in the guy we are dividing into (that guy is officially called the dividend).Think you’ll never be able to master long division? Think about the acronym DMSB, which stands for Divide, Multiply, Subtract, Bring down. Guess what? We are DONE! (No way.) WAY! We used the 6 and the 8. Multiply the 4 and the 2 and put the answer right under the 8: Now, let's go back into our division, multiplication, subtraction loop using the 8! Division: OK, now we're going to do the exact same thing, but with a different number. Hey, those letters go alphabetically!! You can use that to remember it! Hey, we just finished the first chunk of steps! And it wasn't that bad!ĭivision, then multiplication, then subtraction. This is the subtraction step! Do the subtraction.
Multiply the 3 and the 2 and put the answer right under the 6:
