We look at the division of 385748 by 25 
The aim is to understand the frequency of 25 in 385748.

Moving on to step 1:
If we divide 3 by 25, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 25

Step 2:
25 can be fit into 38 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 25 from 38 to get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 25

Moving on to step 3:
If we divide 135 by 25, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 125 away from 135, we end up with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 25

Let's proceed to step 4:
When dividing 107 by 25, we get 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 154.0
If we subtract 100 from 107, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 25

Going ahead to step 5:
25 goes into 74 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 1542.0
Subtract 50 from 74 to get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 25

On to step 6:
The number 25 fits into 248 9 times, leaving a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 15429.0
If we subtract 225 from 248, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
When dividing 230 by 25, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 15429.9
The remainder is 5 after subtracting 225 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
25 goes into 50 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 15429.92
If we take 50 away from 50, 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.

Advancing to step 9:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15429.92
Subtract 0 from 0 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.

Advancing to step 10:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15429.92
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.

The final result is 15429.92 with a remainder of 0.0.
