We look at the division of 22807 by 17 
The aim is to understand the frequency of 17 in 22807.

On to step 1:
If we divide 2 by 17, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 17

Step 2:
17 goes into 22 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 17 from 22 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 17

Going ahead to step 3:
17 goes into 58 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 7 after subtracting 51 from 58.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 17

Moving on to step 4:
The number 17 fits into 70 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 134.0
If we take 68 away from 70, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 17

Moving on to step 5:
If we divide 27 by 17, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 1341.0
The remainder is 10 after subtracting 17 from 27.
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 6:
17 can be fit into 100 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 1341.5
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 1341.58
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 17, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 1341.588
If we take 136 away from 140, we end up 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.

Our division results in 1341.588 with a remaining 0.0004.
