We look at the division of 316572 by 25 
The aim is to understand the frequency of 25 in 316572.

Moving on to step 1:
25 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 25

Step 2:
25 can be fit into 31 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 25 from 31, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 25

On to step 3:
If we divide 66 by 25, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 50 from 66 leaves us with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 25

Going ahead to step 4:
The number 25 fits into 165 6 times, leaving a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Deduct 150 from 165 and we're left with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 25

Advancing to step 5:
25 goes into 157 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 1266.0
Subtracting 150 from 157 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 25

Step 6:
When dividing 72 by 25, we get 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 12662.0
If we subtract 50 from 72, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
If we divide 220 by 25, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 12662.8
If we subtract 200 from 220, 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.

Moving on to step 8:
200 divided by 25 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 12662.88
Subtract 200 from 200 to 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.

The final result is 12662.88 with a remainder of 0.0.
