We're dividing 88698915 by 825 
The aim is to understand the frequency of 825 in 88698915.

Step 1:
When dividing 8 by 825, we get 0 with 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.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 825

Let's proceed to step 2:
825 goes into 88 0 times with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Grab the next digit (6) from the dividend, add it to 88, then carry on: 886 / 825

Going ahead to step 3:
825 can be fit into 886 1 times, resulting in a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 825 from 886 leaves us with 61.
Append the next digit (9) from the dividend to 61 and continue with: 619 / 825

Moving on to step 4:
825 can be fit into 619 0 times, resulting in a remainder of 619.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 619 leaves us with 619.
Fetch the next digit (8) from the dividend, attach it to 619 and continue: 6198 / 825

Step 5:
When dividing 6198 by 825, we get 7 with a remainder of 423.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we subtract 5775 from 6198, we get 423.
Grab the next digit (9) from the dividend, add it to 423, then carry on: 4239 / 825

On to step 6:
If we divide 4239 by 825, we get 5 and a remainder of 114.
Write down 5 as next digit of the result. 
Result so far: 1075.0
If we take 4125 away from 4239, we end up with 114.
Include the next digit (1) from the dividend after 114, then repeat: 1141 / 825

Let's proceed to step 7:
825 can be fit into 1141 1 times, resulting in a remainder of 316.
Use 1 as the next digit of our solution. 
Result so far: 10751.0
Deduct 825 from 1141 and we're left with 316.
Take the next digit (5) from the dividend and append it to 316, then repeat: 3165 / 825

Advancing to step 8:
3165 divided by 825 is 3 with a remainder of 690.
Record the quotient 3 as the next digit in the result. 
Result so far: 107513.0
Subtract 2475 from 3165 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 9:
The number 825 fits into 6900 8 times, leaving a remainder of 300.
Write down 8 as next digit of the result. 
Result so far: 107513.8
The remainder is 300 after subtracting 6600 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 10:
When dividing 3000 by 825, we get 3 with a remainder of 525.
The next digit of our result is 3. 
Result so far: 107513.83
If we subtract 2475 from 3000, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Let's proceed to step 11:
The number 825 fits into 5250 6 times, leaving a remainder of 300.
The next digit of our result is 6. 
Result so far: 107513.836
If we subtract 4950 from 5250, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 12:
The number 825 fits into 3000 3 times, leaving a remainder of 525.
Record the quotient 3 as the next digit in the result. 
Result so far: 107513.8363
Subtracting 2475 from 3000 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 13:
825 can be fit into 5250 6 times, resulting in a remainder of 300.
Record the quotient 6 as the next digit in the result. 
Result so far: 107513.83636
Deduct 4950 from 5250 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 14:
3000 divided by 825 is 3 with a remainder of 525.
Write down 3 as next digit of the result. 
Result so far: 107513.836363
Subtracting 2475 from 3000 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 15:
5250 divided by 825 is 6 with a remainder of 300.
Use 6 as the next digit of our solution. 
Result so far: 107513.8363636
If we subtract 4950 from 5250, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 16:
825 can be fit into 3000 3 times, resulting in a remainder of 525.
Write down 3 as next digit of the result. 
Result so far: 107513.83636363
The remainder is 525 after subtracting 2475 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

After the division, we end up with 107513.83636363 and a remainder of 5.25e-07.
