We look at the division of 961706 by 88 
The aim is to understand the frequency of 88 in 961706.

Step 1:
The number 88 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 88

Advancing to step 2:
The number 88 fits into 96 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 88 from 96 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 88

Going ahead to step 3:
88 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 88

On to step 4:
817 divided by 88 is 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtract 792 from 817 to get 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 88

On to step 5:
When dividing 250 by 88, we get 2 with a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 1092.0
If we take 176 away from 250, we end up with 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 88

Going ahead to step 6:
The number 88 fits into 746 8 times, leaving a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 10928.0
If we take 704 away from 746, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
The number 88 fits into 420 4 times, leaving a remainder of 68.
The next digit of our result is 4. 
Result so far: 10928.4
Deduct 352 from 420 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
680 divided by 88 is 7 with a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 10928.47
Subtract 616 from 680 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
88 goes into 640 7 times with a remainder of 24.
The next digit of our result is 7. 
Result so far: 10928.477
If we subtract 616 from 640, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 10928.477 with a remaining 0.0024.
