We're dividing 128155 by 17 
The aim is to understand the frequency of 17 in 128155.

Advancing to step 1:
If we divide 1 by 17, we get 0 and 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.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 17

Moving on to step 2:
If we divide 12 by 17, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 17

Going ahead to step 3:
128 divided by 17 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 119 from 128 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 17

Going ahead to step 4:
17 goes into 91 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
The remainder is 6 after subtracting 85 from 91.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 17

Going ahead to step 5:
When dividing 65 by 17, we get 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 753.0
Subtracting 51 from 65 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 17

Moving on to step 6:
If we divide 145 by 17, we get 8 and a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 7538.0
If we subtract 136 from 145, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 17, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7538.5
Subtracting 85 from 90 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
50 divided by 17 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 7538.52
Subtracting 34 from 50 leaves us 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:
17 goes into 160 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 7538.529
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
When dividing 70 by 17, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 7538.5294
The remainder is 2 after subtracting 68 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
The number 17 fits into 20 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7538.52941
Subtracting 17 from 20 leaves us 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.

Moving on to step 12:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 7538.529411
Subtracting 17 from 30 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 7538.529411 with a remaining 1.3e-06.
