Let's divide 129270 by 25
The aim is to understand the frequency of 25 in 129270.

On to step 1:
The number 25 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 25

Moving on to step 2:
The number 25 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 25

Step 3:
The number 25 fits into 129 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 125 from 129 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 25

Advancing to step 4:
If we divide 42 by 25, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 25 from 42 and we're left with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 25

Let's proceed to step 5:
When dividing 177 by 25, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.0
The remainder is 2 after subtracting 175 from 177.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 25

On to step 6:
25 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5170.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
The number 25 fits into 200 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 5170.8
If we take 200 away from 200, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5170.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5170.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 5170.8 with a balance of 0.0.
