We look at the division of 817376 by 17 
The aim is to understand the frequency of 17 in 817376.

On to step 1:
When dividing 8 by 17, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 17

Step 2:
17 can be fit into 81 4 times, resulting in a remainder of 13.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 68 from 81 to get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 17

Moving on to step 3:
When dividing 137 by 17, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 136 away from 137, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 17

Let's proceed to step 4:
The number 17 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 480.0
If we subtract 0 from 13, we get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 17

Going ahead to step 5:
When dividing 137 by 17, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 4808.0
If we take 136 away from 137, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 17

Advancing to step 6:
The number 17 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 48080.0
Subtracting 0 from 16 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 7:
160 divided by 17 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 48080.9
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.

On to step 8:
If we divide 70 by 17, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 48080.94
Subtract 68 from 70 to 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.

On to step 9:
The number 17 fits into 20 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 48080.941
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: 48080.9411
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.

The quotient of the division is 48080.9411, and the remainder is 0.00013.
