We're dividing 191521 by 17 
The aim is to understand the frequency of 17 in 191521.

Step 1:
If we divide 1 by 17, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 17

Advancing to step 2:
If we divide 19 by 17, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 17 from 19.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 17

On to step 3:
When dividing 21 by 17, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 17 away from 21, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 17

Moving on to step 4:
17 can be fit into 45 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we take 34 away from 45, we end up with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 17

Advancing to step 5:
17 can be fit into 112 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 1126.0
Subtract 102 from 112 to get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 17

Let's proceed to step 6:
17 goes into 101 5 times with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 11265.0
Subtracting 85 from 101 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.

Step 7:
17 goes into 160 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 11265.9
Deduct 153 from 160 and we're left 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.

On to step 8:
17 can be fit into 70 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 11265.94
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.

Going ahead to step 9:
17 goes into 20 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 11265.941
Subtract 17 from 20 to get 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 10:
If we divide 30 by 17, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 11265.9411
Subtract 17 from 30 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 11265.9411 with a balance of 0.00013.
