We're dividing 12608666 by 136 
The aim is to understand the frequency of 136 in 12608666.

Advancing to step 1:
1 divided by 136 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 136

Step 2:
The number 136 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 136

Let's proceed to step 3:
When dividing 126 by 136, we get 0 with a remainder of 126.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 126 leaves us with 126.
Grab the next digit (0) from the dividend, add it to 126, then carry on: 1260 / 136

Moving on to step 4:
If we divide 1260 by 136, we get 9 and a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 1224 from 1260, we get 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 136

Moving on to step 5:
136 goes into 368 2 times with a remainder of 96.
The next digit of our result is 2. 
Result so far: 92.0
Deduct 272 from 368 and we're left with 96.
Include the next digit (6) from the dividend after 96, then repeat: 966 / 136

Going ahead to step 6:
966 divided by 136 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 927.0
The remainder is 14 after subtracting 952 from 966.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 136

Going ahead to step 7:
When dividing 146 by 136, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 9271.0
Subtracting 136 from 146 leaves us with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 136

On to step 8:
When dividing 106 by 136, we get 0 with a remainder of 106.
The number 0 becomes the next digit in our result. 
Result so far: 92710.0
The remainder is 106 after subtracting 0 from 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 9:
If we divide 1060 by 136, we get 7 and a remainder of 108.
Record the quotient 7 as the next digit in the result. 
Result so far: 92710.7
The remainder is 108 after subtracting 952 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 10:
The number 136 fits into 1080 7 times, leaving a remainder of 128.
The number 7 becomes the next digit in our result. 
Result so far: 92710.77
Deduct 952 from 1080 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 92710.77, and the remainder is 0.128.
