We look at the division of 257364 by 25 
The aim is to understand the frequency of 25 in 257364.

Let's proceed to step 1:
The number 25 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 25

Going ahead to step 2:
25 divided by 25 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 25 from 25 leaves us with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 25

On to step 3:
If we divide 7 by 25, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 25

Advancing to step 4:
25 goes into 73 2 times with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we subtract 50 from 73, we get 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 25

On to step 5:
When dividing 236 by 25, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1029.0
The remainder is 11 after subtracting 225 from 236.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 25

On to step 6:
If we divide 114 by 25, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 10294.0
The remainder is 14 after subtracting 100 from 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 25 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 10294.5
Deduct 125 from 140 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
When dividing 150 by 25, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 10294.56
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10294.56
Subtracting 0 from 0 leaves us 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 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10294.56
Deduct 0 from 0 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 10294.56 and a remainder of 0.0.
