We look at the division of 122016 by 17 
The aim is to understand the frequency of 17 in 122016.

On to step 1:
1 divided by 17 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 17

Moving on to step 2:
17 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 17

Moving on to step 3:
122 divided by 17 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 119 from 122, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 17

Moving on to step 4:
When dividing 30 by 17, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we subtract 17 from 30, we get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 17

Advancing to step 5:
If we divide 131 by 17, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 717.0
Deduct 119 from 131 and we're left with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 17

Moving on to step 6:
When dividing 126 by 17, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7177.0
The remainder is 7 after subtracting 119 from 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
17 goes into 70 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 7177.4
If we subtract 68 from 70, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 17, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 7177.41
Deduct 17 from 20 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.

Going ahead to step 9:
17 can be fit into 30 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 7177.411
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.

The final result is 7177.411 with a remainder of 0.0013.
