We divide 809318 by 17
The aim is to understand the frequency of 17 in 809318.

Step 1:
If we divide 8 by 17, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 17

On to step 2:
17 can be fit into 80 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 68 from 80, we get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 17

Advancing to step 3:
When dividing 129 by 17, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Deduct 119 from 129 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 17

Step 4:
17 can be fit into 103 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 476.0
If we take 102 away from 103, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 17

On to step 5:
11 divided by 17 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 4760.0
The remainder is 11 after subtracting 0 from 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 17

Let's proceed to step 6:
When dividing 118 by 17, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 47606.0
The remainder is 16 after subtracting 102 from 118.
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:
The number 17 fits into 160 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 47606.9
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
17 goes into 70 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 47606.94
If we take 68 away from 70, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
20 divided by 17 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 47606.941
The remainder is 3 after subtracting 17 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
When dividing 30 by 17, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 47606.9411
The remainder is 13 after subtracting 17 from 30.
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 47606.9411 with a remainder of 0.00013.
