824688 ÷ 25 
The aim is to understand the frequency of 25 in 824688.

Advancing to step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 25

On to step 2:
If we divide 82 by 25, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 75 away from 82, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 25

On to step 3:
When dividing 74 by 25, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we subtract 50 from 74, we get 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 25

Let's proceed to step 4:
25 goes into 246 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 329.0
Subtracting 225 from 246 leaves us with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 25

Going ahead to step 5:
The number 25 fits into 218 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 3298.0
The remainder is 18 after subtracting 200 from 218.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 25

Going ahead to step 6:
When dividing 188 by 25, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 32987.0
The remainder is 13 after subtracting 175 from 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 25, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 32987.5
If we subtract 125 from 130, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
25 goes into 50 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 32987.52
The remainder is 0 after subtracting 50 from 50.
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.
The number 0 becomes the next digit in our result. 
Result so far: 32987.52
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.

Advancing to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 32987.52
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.

Our division results in 32987.52 with a remaining 0.0.
