We divide 315347 by 25
The aim is to understand the frequency of 25 in 315347.

On to step 1:
3 divided by 25 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 25

Moving on to step 2:
25 goes into 31 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 25 away from 31, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 25

Let's proceed to step 3:
65 divided by 25 is 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 50 from 65, we get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 25

Going ahead to step 4:
25 goes into 153 6 times with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 126.0
Subtract 150 from 153 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 25

Let's proceed to step 5:
34 divided by 25 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1261.0
If we subtract 25 from 34, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 25

Let's proceed to step 6:
When dividing 97 by 25, we get 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 12613.0
If we subtract 75 from 97, 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.

Let's proceed to step 7:
25 can be fit into 220 8 times, resulting in a remainder of 20.
The next digit of our result is 8. 
Result so far: 12613.8
The remainder is 20 after subtracting 200 from 220.
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:
When dividing 200 by 25, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 12613.88
Deduct 200 from 200 and we're left 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.

After the division, we end up with 12613.88 and a remainder of 0.0.
