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 210 divided by 30 using long division.
What you can expect to learn:
- How to use long division to calculate 210 divided by 30
- 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 210 divided by 30 calculation:
You need to know which numbers are involved here and in what capacity.
- The number that is being divided is 210 and is called the dividend.
- The second number that is being divided by is 30 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.
210 divided by 30 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:
30⟌210
Step 2:
The divisor (30) goes into the first digit of the dividend (2), 0 times. Why?
It’s simple. You ask yourself, can you put 30 into the first digit 2? You can’t. So if you can’t, then the answer is 0.
So we put 0 at the top as below:
0
30⟌210
Step 3:
We multiply the divisor (30) by the result (0) in the previous step.
30x 0 = 0
We put the 0 below:
0
30⟌210
0
Step 4:
Now we have to subtract the result from the previous step (0) from the first digit of dividend.
2 – 0 = 2
We put the answer in our calculations as shown below:
0
30⟌210
– 0
⏤⏤
2
Step 5:
Next, we need to pull the second and third digits of the dividend down as well. So it looks like this:
0
30⟌210
– 0
⏤⏤
210
Step 6:
Since we were not able to put 30 into 2 in our step 2, we will now try to put 30, our divisor, into 21.
The question to ask is, how many times can 30 go into 21?
The diviser, 30, can go into 21, 0 time(s).
So we add 0 into the quotient as below:
00
30⟌210
– 0
⏤
210
Step 7:
We multiply the divisor 30 by the result in the previous step.
30 x 0 = 0
Then we add the answer to our division process like shown below:
00
30⟌210
– 0
⏤
210
0
Step 8:
Now we have to subtract our result in the step above from the number above it.
In this case 21 – 0 = 21
See below:
00
30⟌210
– 0
⏤⏤
210
– 0
⏤⏤
21
Step 9:
Next, we need to pull the third digit of the dividend down as well. So it looks like this:
00
30⟌210
– 0
⏤⏤
210
– 0
⏤⏤
210
Step 10:
Since we were not able to put 30 into 21, we will now try to put 30, our divisor, into 210.
The question to ask yourself is, how many times can 30 go into 210?
The diviser, 30, can go into 210, 7 time(s).
So we add 7 into the quotient as below:
005
30⟌210
– 0
⏤⏤
210
– 0
⏤⏤
210
Step 11:
We multiply the divisor 30 by the result in the previous step.
30 x 7 = 210
Then we add the answer to our division process like shown below:
005
30⟌210
– 0
⏤⏤
210
– 0
⏤⏤
210
210
Step 12:
Now we have to subtract our result in the step above from the number above it.
In this case 210 – 210 = 0
See below:
005
30⟌210
– 0
⏤⏤
210
– 0
⏤⏤
210
210
⏤⏤
0
What is the answer to 210 divided by 30?
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 210 divided by 30 is the quotient, 7, that we got above.
You can do 210 divided by 30 using other ways like:
-
A calculator
If you typed in 210÷30 on a calculator you will get 7 as the result.
-
Mixed Fraction
If you divided 210/30 and wanted the answer as a mixed fraction, your answer will be 7 0/30 where 0 is the remainder, 7 is the quotient and 30 is the divisor from our calculations in step 8 above.
