We look at the division of 691227 by 88 
The aim is to understand the frequency of 88 in 691227.

On to step 1:
6 divided by 88 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 88

Moving on to step 2:
88 goes into 69 0 times with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 88

Advancing to step 3:
691 divided by 88 is 7 with a remainder of 75.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 616 from 691 to get 75.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 88

Advancing to step 4:
88 can be fit into 752 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we take 704 away from 752, we end up with 48.
Fetch the next digit (2) from the dividend, attach it to 48 and continue: 482 / 88

Moving on to step 5:
If we divide 482 by 88, we get 5 and a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 785.0
Subtracting 440 from 482 leaves us with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 88

Moving on to step 6:
427 divided by 88 is 4 with a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 7854.0
If we subtract 352 from 427, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 7:
88 goes into 750 8 times with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 7854.8
The remainder is 46 after subtracting 704 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
88 goes into 460 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 7854.85
If we subtract 440 from 460, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
200 divided by 88 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 7854.852
If we take 176 away from 200, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
240 divided by 88 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 7854.8522
Deduct 176 from 240 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 7854.8522, and the remainder is 0.00064.
