![]() ![]() Thanks for watching and happy studying!įirst, set up the problem for long division by writing the divisor, 9, to the left of the long division symbol and the dividend, 5.58, to its right. I hope this review of dividing a decimal by a whole number was helpful. I’m going to start by setting up my long division problem.Īnd finally, I’ll complete the long division process.Īfter adding an extra zero so I wasn’t left with a remainder, I got 0.7744. Then, once you’ve got it, press play and see if it matches up with mine. I’ll give you the problem and then I want you to pause the video and find the answer yourself. I want to do one more example, but this time try it on your own first. This is because we already have a decimal point and you can’t have two.Īfter adding two zeroes, we finally get an answer without a remainder, 0.49325. However, instead of adding a decimal and a zero, you will just add a zero and continue dividing. ![]() With our example, you are going to do almost the same thing. Adding a decimal point and zeroes after it doesn’t change the value of the original number because it just means adding zero parts to the whole. You can do this because 1.0 is the same as 1, which is also the same as 1.00. If you recall when you first learned how to long divide, you were most likely taught to add a decimal and a zero and then keep dividing and adding zeroes until you no longer have a remainder. In this problem, we encounter something we haven’t before, a remainder. Then, place the decimal point in the correct spot. This example will require a couple of extra steps that the last few didn’t. Then, add your decimal point in the appropriate place.Īnd from there, divide as you would typically with a long division problem. Write twenty-five and subtract which gives us zero.įirst, set up your long division problem. Five goes into twenty-five five times so we write a five up here. Now, we have two we’re gonna bring down this five down. Five goes into twenty-seven five times so we’re gonna write a five up here. This gives us two and we’re gonna bring down the seven. Five goes into thirty-two six times so we’re gonna write a six up here. This gives us three and we bring down our two. Then, place your decimal point in the appropriate place in your quotient.Īnd now, divide as you would typically with long division.įive goes into eight one time so we’re gonna put a one up here. This tells us that your grandma should give 85 cents to each of her grandchildren.įirst, set it up like a long division problem. Subtract twenty-five and we’re left with zero. Five goes into twenty-five five times so we right a five up here. This gives us two then we bring the five down to get twenty-five. So, we write a forty underneath and subtract. So, 5 cannot go into four anytime so we’re gonna put a zero here and move on. You no longer need to think about that decimal. The only difference being that we put a decimal point in our answer right above where it is placed in our problem, like this: Then we will work the problem exactly like we would any other long division problem. When dividing a decimal by a whole number, you want to set up your division just like you would for regular long division, like this: Let’s go over the process of how to divide with decimals using this example. Consider this example: your grandma has $4.25 in coins and she wants to split the money evenly among her 5 grandkids. Another common way you will see division with decimals is involving money. ![]() But, if you had part of a whole pizza left, say four slices out of whole pizza made of 8, that’s not as weird to split with some friends. If you had part of a slice of pizza because you had eaten the other part already, it would be a little weird to split the rest of that part with a couple of friends. Hi, and welcome to this video on dividing decimals by whole numbers.ĭecimals represent part of a whole, so it may seem a little unusual to divide a part of something into different groups. ![]()
