888475 ÷ 25 
The aim is to understand the frequency of 25 in 888475.

Step 1:
If we divide 8 by 25, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 25

On to step 2:
25 goes into 88 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 75 from 88 and we're left with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 25

On to step 3:
25 goes into 138 5 times with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 13 after subtracting 125 from 138.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 25

Let's proceed to step 4:
25 goes into 134 5 times with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Deduct 125 from 134 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 25

Going ahead to step 5:
The number 25 fits into 97 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3553.0
Subtract 75 from 97 to get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 25

Let's proceed to step 6:
25 can be fit into 225 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 35539.0
Deduct 225 from 225 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.

Going ahead to step 7:
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: 35539.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 35539.0
If we take 0 away from 0, 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.

After the division, we end up with 35539.0 and a remainder of 0.0.
