We look at the division of 807037 by 25 
The aim is to understand the frequency of 25 in 807037.

Let's proceed to step 1:
When dividing 8 by 25, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 25

Advancing to step 2:
If we divide 80 by 25, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 5 after subtracting 75 from 80.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 25

Advancing to step 3:
When dividing 57 by 25, we get 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtracting 50 from 57 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 25

Moving on to step 4:
25 goes into 70 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 322.0
Deduct 50 from 70 and we're left with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 25

Step 5:
203 divided by 25 is 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 3228.0
Subtract 200 from 203 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 25

On to step 6:
37 divided by 25 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 32281.0
The remainder is 12 after subtracting 25 from 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
When dividing 120 by 25, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 32281.4
If we take 100 away from 120, we end up with 20.
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.
The number 8 becomes the next digit in our result. 
Result so far: 32281.48
The remainder is 0 after subtracting 200 from 200.
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 9:
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: 32281.48
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:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 32281.48
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.

Our division results in 32281.48 with a remaining 0.0.
