806819 divided by 17 
The aim is to understand the frequency of 17 in 806819.

Moving on to step 1:
The number 17 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 17

Advancing to step 2:
When dividing 80 by 17, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 68 from 80 to get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 17

Going ahead to step 3:
If we divide 126 by 17, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 47.0
If we subtract 119 from 126, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 17

On to step 4:
78 divided by 17 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
If we take 68 away from 78, we end up with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 17

Let's proceed to step 5:
The number 17 fits into 101 5 times, leaving a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 4745.0
If we subtract 85 from 101, we get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 17

Going ahead to step 6:
If we divide 169 by 17, we get 9 and a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 47459.0
Subtract 153 from 169 to get 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:
If we divide 160 by 17, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 47459.9
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.

Going ahead to step 8:
When dividing 70 by 17, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 47459.94
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.

Moving on to step 9:
20 divided by 17 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 47459.941
If we take 17 away from 20, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
The number 17 fits into 30 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 47459.9411
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 final result is 47459.9411 with a remainder of 0.00013.
