We look at the division of 853396 by 88 
The aim is to understand the frequency of 88 in 853396.

Going ahead to step 1:
88 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 88

Step 2:
88 can be fit into 85 0 times, resulting in a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Append the next digit (3) from the dividend to 85 and continue with: 853 / 88

Moving on to step 3:
The number 88 fits into 853 9 times, leaving a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 61 after subtracting 792 from 853.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 88

Moving on to step 4:
When dividing 613 by 88, we get 6 with a remainder of 85.
The next digit of our result is 6. 
Result so far: 96.0
Subtract 528 from 613 to get 85.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 88

On to step 5:
When dividing 859 by 88, we get 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 969.0
The remainder is 67 after subtracting 792 from 859.
Include the next digit (6) from the dividend after 67, then repeat: 676 / 88

On to step 6:
The number 88 fits into 676 7 times, leaving a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 9697.0
Deduct 616 from 676 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
88 can be fit into 600 6 times, resulting in a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 9697.6
Subtracting 528 from 600 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 8:
The number 88 fits into 720 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 9697.68
Deduct 704 from 720 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
88 can be fit into 160 1 times, resulting in a remainder of 72.
The next digit of our result is 1. 
Result so far: 9697.681
Subtract 88 from 160 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
720 divided by 88 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 9697.6818
Deduct 704 from 720 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
160 divided by 88 is 1 with a remainder of 72.
The next digit of our result is 1. 
Result so far: 9697.68181
Deduct 88 from 160 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
When dividing 720 by 88, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 9697.681818
If we take 704 away from 720, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
The number 88 fits into 160 1 times, leaving a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 9697.6818181
Subtract 88 from 160 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
The number 88 fits into 720 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 9697.68181818
Subtract 704 from 720 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 9697.68181818 with a remainder of 1.6e-08.
