We look at the division of 670651 by 88 
The aim is to understand the frequency of 88 in 670651.

Advancing to step 1:
If we divide 6 by 88, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 88

On to step 2:
If we divide 67 by 88, we get 0 and a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 88

Moving on to step 3:
88 can be fit into 670 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 616 from 670 leaves us with 54.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 88

Advancing to step 4:
The number 88 fits into 546 6 times, leaving a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 528 from 546 to get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 88

Advancing to step 5:
If we divide 185 by 88, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 762.0
If we take 176 away from 185, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 88

Let's proceed to step 6:
91 divided by 88 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 7621.0
Deduct 88 from 91 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
88 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 7621.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 88 fits into 300 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 7621.03
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
88 can be fit into 360 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 7621.034
The remainder is 8 after subtracting 352 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
88 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 7621.034
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
When dividing 800 by 88, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 7621.03409
Subtract 792 from 800 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
If we divide 80 by 88, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 7621.03409
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
The number 88 fits into 800 9 times, leaving a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 7621.0340909
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
80 divided by 88 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 7621.0340909
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 7621.0340909 with a remainder of 8e-08.
