Using long division can be a challenge if you don’t know how to do it well. In this article, we will teach you how to calculate 128 divided by 32 using long division.
What you can expect to learn:
- How to use long division to calculate 128 divided by 32
- How to do the calculation faster so that you don’t spend too much time on it
- The main rules to apply when calculating any divisions using long division
Now that we have set our objectives for this exercise, let’s proceed to do it!
Understanding the parts of the 128 divided by 32 calculation:
You need to know which numbers are involved here and in what capacity.
- The number that is being divided is 128 and is called the dividend.
- The second number that is being divided by is 32 and is called the divisor.
- The result that we shall get after doing the calculation is called the quotient.
Now that we understand the parts of our division, we can go ahead and start doing the maths.
128 divided by 32 step-by-step process:
Step 1:
We begin by setting up our divisor on the left side and the dividend on the right side. Here is how:
32⟌128
Step 2:
The divisor (32) goes into the first digit of the dividend (1), 0 times. Why?
It’s simple. You ask yourself, can you put 32 into the first digit 1? You can’t. So if you can’t, then the answer is 0.
So we put 0 at the top as below:
0
32⟌128
Step 3:
We multiply the divisor (32) by the result (0) in the previous step.
32x 0 = 0
We put the 0 below:
0
32⟌128
0
Step 4:
Now we have to subtract the result from the previous step (0) from the first digit of dividend.
1 – 0 = 1
We put the answer in our calculations as shown below:
0
32⟌128
– 0
⏤⏤
1
Step 5:
Next, we need to pull the second and third digits of the dividend down as well. So it looks like this:
0
32⟌128
– 0
⏤⏤
128
Step 6:
Since we were not able to put 32 into 1 in our step 2, we will now try to put 32, our divisor, into 12.
The question to ask is, how many times can 32 go into 12?
The diviser, 32, can go into 12, 0 time(s).
So we add 0 into the quotient as below:
00
32⟌128
– 0
⏤
128
Step 7:
We multiply the divisor 32 by the result in the previous step.
32 x 0 = 0
Then we add the answer to our division process like shown below:
00
32⟌128
– 0
⏤
128
0
Step 8:
Now we have to subtract our result in the step above from the number above it.
In this case 12 – 0 = 12
See below:
00
32⟌128
– 0
⏤⏤
128
– 0
⏤⏤
12
Step 9:
Next, we need to pull the third digit of the dividend down as well. So it looks like this:
00
32⟌128
– 0
⏤⏤
128
– 0
⏤⏤
128
Step 10:
Since we were not able to put 32 into 12, we will now try to put 32, our divisor, into 128.
The question to ask yourself is, how many times can 32 go into 128?
The diviser, 32, can go into 128, 4 time(s).
So we add 4 into the quotient as below:
005
32⟌128
– 0
⏤⏤
128
– 0
⏤⏤
128
Step 11:
We multiply the divisor 32 by the result in the previous step.
32 x 4 = 128
Then we add the answer to our division process like shown below:
005
32⟌128
– 0
⏤⏤
128
– 0
⏤⏤
128
128
Step 12:
Now we have to subtract our result in the step above from the number above it.
In this case 128 – 128 = 0
See below:
005
32⟌128
– 0
⏤⏤
128
– 0
⏤⏤
128
128
⏤⏤
0
What is the answer to 128 divided by 32?
Because we don’t have any other digits to pull down from our dividend, the 0 at the end of the step above sums up the last step of our calculations.
The answer to 128 divided by 32 is the quotient, 4, that we got above.
You can do 128 divided by 32 using other ways like:
-
A calculator
If you typed in 128÷32 on a calculator you will get 4 as the result.
-
Mixed Fraction
If you divided 128/32 and wanted the answer as a mixed fraction, your answer will be 4 0/32 where 0 is the remainder, 4 is the quotient and 32 is the divisor from our calculations in step 8 above.
