Hello this is Professor Sampson and

I’m going to help you with Squire’s section 1.7 long division. I will be showing you how to do long division on your calculator two ways. The first way is the easier way and I’m going to give you an

example. For example, 895 divided by 8 895 divided by 8 and we’re looking

for a remainder 895 divided by 8 and you see the slash comes up. When you hit enter you’re going to get a

whole number and a decimal. This is not your

remainder. How do you find the remainder? The first

thing you’re going to do is subtract out your whole number. So you gonna going to plug in minus 111 and hit enter and that will leave you with your

decimal. Once you have your decimal you gonna multiply that by whatever

your denominator was in our case it is 8. We are going to multiply it by 8, all we have to do is times 8, and

that’s going to be a remainder. So your answer is one 111 remainder 7. Let’s try another problem to see if you’re able to do it. 739

divided by 6 739 divided by 6. You need your whole number first so when

you hit enter you get 123. That’s your whole number that you are going to put in MyMathLab. You’re going to subtract out your 123

leaving you with the decimal and this time your gonna multiply your

decimal times what? This time you gonna multiply it by six

because six is your denominator. times six leaving you with 1 so your answer is 123 remainder 1. Lets do two more examples. The next

example, I’m going to do is 942 divided by 7. 942 divided by 7 Your whole numbers gonna be 134 you will

subtract out your 134 leaving you with the decimal and this time your gonna multiply your decimal times 7 because seven is the denominator of the

problem… times 7 so your finally answer is 134 with a remainder of 4..your last example I will be doing is 4427 divided by 6 4427 divided by 6. Again that’s going to leave you with your whole number and your decimal you wanna subtract out your whole number

minus 737, your left with your decimal and this time you gonna

multiply this decimal by 6 As you notice, I’m not clear in the

calculated as I do it. Please resist urge to clear your

calculator, just keep going. So in this case my answer is 737 remainder 5. This is how you find your remainder using the TI 84 plus calculator. You can also use this method with any

other regular calculator. That concludes this topic from Squires section 1.7 on dividing whole numbers.
