We're dividing 587163 by 25 
The aim is to understand the frequency of 25 in 587163.

Moving on to step 1:
The number 25 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 25

Going ahead to step 2:
The number 25 fits into 58 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 50 from 58, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 25

Going ahead to step 3:
The number 25 fits into 87 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 75 from 87 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 25

On to step 4:
When dividing 121 by 25, we get 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
If we subtract 100 from 121, we get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 25

Step 5:
25 goes into 216 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 2348.0
The remainder is 16 after subtracting 200 from 216.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 25

Let's proceed to step 6:
163 divided by 25 is 6 with a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 23486.0
Deduct 150 from 163 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
When dividing 130 by 25, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 23486.5
The remainder is 5 after subtracting 125 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
If we divide 50 by 25, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 23486.52
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:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23486.52
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.

Going ahead to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23486.52
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.

The quotient of the division is 23486.52, and the remainder is 0.0.
