We look at the division of 828673 by 17 
The aim is to understand the frequency of 17 in 828673.

Step 1:
If we divide 8 by 17, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 17

Step 2:
17 goes into 82 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 68 from 82 and we're left with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 17

Advancing to step 3:
17 goes into 148 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 136 from 148 to get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 17

On to step 4:
When dividing 126 by 17, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 487.0
The remainder is 7 after subtracting 119 from 126.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 17

On to step 5:
When dividing 77 by 17, we get 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 4874.0
The remainder is 9 after subtracting 68 from 77.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 17

Going ahead to step 6:
93 divided by 17 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 48745.0
If we subtract 85 from 93, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
When dividing 80 by 17, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 48745.4
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 17 fits into 120 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 48745.47
If we subtract 119 from 120, we 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 9:
If we divide 10 by 17, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 48745.47
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
If we divide 100 by 17, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 48745.4705
The remainder is 15 after subtracting 85 from 100.
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 11:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 48745.47058
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.

On to step 12:
17 goes into 140 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 48745.470588
Subtracting 136 from 140 leaves us with 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 48745.470588, and the remainder is 4e-07.
