We look at the division of 427346 by 25 
The aim is to understand the frequency of 25 in 427346.

Going ahead to step 1:
When dividing 4 by 25, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 25

Moving on to step 2:
42 divided by 25 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 25 from 42 to get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 25

Let's proceed to step 3:
177 divided by 25 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 2 after subtracting 175 from 177.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 25

Going ahead to step 4:
23 divided by 25 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 25

Advancing to step 5:
25 goes into 234 9 times with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 1709.0
If we take 225 away from 234, we end up with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 25

Step 6:
96 divided by 25 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 17093.0
Subtracting 75 from 96 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
If we divide 210 by 25, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 17093.8
Deduct 200 from 210 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 25, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 17093.84
Subtract 100 from 100 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.

On to step 9:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17093.84
If we subtract 0 from 0, we 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.

Step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17093.84
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.

The final result is 17093.84 with a remainder of 0.0.
