We look at the division of 219527 by 25 
The aim is to understand the frequency of 25 in 219527.

Let's proceed to step 1:
25 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 25

Going ahead to step 2:
25 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 25

Going ahead to step 3:
When dividing 219 by 25, we get 8 with a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 200 from 219, we get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 25

Moving on to step 4:
The number 25 fits into 195 7 times, leaving a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Deduct 175 from 195 and we're left with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 25

Going ahead to step 5:
25 can be fit into 202 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 878.0
The remainder is 2 after subtracting 200 from 202.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 25

Going ahead to step 6:
25 goes into 27 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 8781.0
Subtracting 25 from 27 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 25, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8781.0
If we take 0 away from 20, we end up with 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 8:
If we divide 200 by 25, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8781.08
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8781.08
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8781.08
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.

The final result is 8781.08 with a remainder of 0.0.
