We're dividing 12666 by 17 
The aim is to understand the frequency of 17 in 12666.

Moving on to step 1:
If we divide 1 by 17, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 17

Step 2:
When dividing 12 by 17, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 17

Moving on to step 3:
17 can be fit into 126 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 119 from 126 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 17

Let's proceed to step 4:
17 can be fit into 76 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we take 68 away from 76, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 17

Let's proceed to step 5:
The number 17 fits into 86 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 745.0
Subtract 85 from 86 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
10 divided by 17 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 745.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 745.05
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
When dividing 150 by 17, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 745.058
Subtract 136 from 150 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
17 goes into 140 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 745.0588
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 745.0588, and the remainder is 4e-05.
