We're dividing 815088 by 88 
The aim is to understand the frequency of 88 in 815088.

Advancing to step 1:
The number 88 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 88

Moving on to step 2:
88 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 88

Advancing to step 3:
If we divide 815 by 88, we get 9 and a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 792 from 815 leaves us with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 88

Let's proceed to step 4:
The number 88 fits into 230 2 times, leaving a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 92.0
Subtract 176 from 230 to get 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 88

Moving on to step 5:
The number 88 fits into 548 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 926.0
If we take 528 away from 548, we end up with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 88

Going ahead to step 6:
When dividing 208 by 88, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 9262.0
If we take 176 away from 208, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
88 goes into 320 3 times with a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 9262.3
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
If we divide 560 by 88, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 9262.36
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
88 goes into 320 3 times with a remainder of 56.
The next digit of our result is 3. 
Result so far: 9262.363
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
If we divide 560 by 88, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 9262.3636
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
88 goes into 320 3 times with a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 9262.36363
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
When dividing 560 by 88, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 9262.363636
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
The number 88 fits into 320 3 times, leaving a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 9262.3636363
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
560 divided by 88 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 9262.36363636
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 9262.36363636 with a remainder of 3.2e-08.
