What you can expect to learn:
- How to use long division to calculate 125 divided by 25
- 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 125 divided by 25 calculation:
You need to know which numbers are involved here and in what capacity.
- The number that is being divided is 125 and is called the dividend.
- The second number that is being divided by is 25 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.
125 divided by 25 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:
25⟌125
Step 2:
The divisor (25) goes into the first digit of the dividend (1), 0 times. Why?
It’s simple. You ask yourself, can you put 25 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
25⟌125
Step 3:
We multiply the divisor (25) by the result (0) in the previous step.
25x 0 = 0
We put the 0 below:
0
25⟌125
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
25⟌125
– 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
25⟌125
– 0
⏤⏤
125
Step 6:
Since we were not able to put 25 into 1 in our step 2, we will now try to put 25, our divisor, into 12.
The question to ask is, how many times can 25 go into 12?
The diviser, 25, can go into 12, 0 time(s).
So we add 0 into the quotient as below:
00
25⟌125
– 0
⏤
125
Step 7:
We multiply the divisor 25 by the result in the previous step.
25 x 0 = 0
Then we add the answer to our division process like shown below:
00
25⟌125
– 0
⏤
125
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
25⟌125
– 0
⏤⏤
125
– 0
⏤⏤
12
Step 9:
Next, we need to pull the third digit of the dividend down as well. So it looks like this:
00
25⟌125
– 0
⏤⏤
125
– 0
⏤⏤
125
Step 10:
Since we were not able to put 25 into 12, we will now try to put 25, our divisor, into 125.
The question to ask yourself is, how many times can 25 go into 125?
The diviser, 25, can go into 125, 5 time(s).
So we add 5 into the quotient as below:
005
25⟌125
– 0
⏤⏤
125
– 0
⏤⏤
125
Step 11:
We multiply the divisor 25 by the result in the previous step.
25 x 5 = 125
Then we add the answer to our division process like shown below:
005
25⟌125
– 0
⏤⏤
125
– 0
⏤⏤
125
125
Step 12:
Now we have to subtract our result in the step above from the number above it.
In this case 125 – 125 = 0
See below:
005
25⟌125
– 0
⏤⏤
125
– 0
⏤⏤
125
125
⏤⏤
0
What is the answer to 125 divided by 25?
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 125 divided by 25 is the quotient, 5, that we got above.
You can do 125 divided by 25 using other ways like:
-
A calculator
If you typed in 125÷25 on a calculator you will get 5 as the result.
-
Mixed Fraction
If you divided 125/25 and wanted the answer as a mixed fraction, your answer will be 5 0/25 where 0 is the remainder, 5 is the quotient and 25 is the divisor from our calculations in step 8 above.
