We divide 689020 by 17
The aim is to understand the frequency of 17 in 689020.

On to step 1:
When dividing 6 by 17, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 17

Moving on to step 2:
17 can be fit into 68 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 0 after subtracting 68 from 68.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 17

Moving on to step 3:
If we divide 9 by 17, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 17

Let's proceed to step 4:
17 goes into 90 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 405.0
Subtracting 85 from 90 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 17

Advancing to step 5:
If we divide 52 by 17, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 4053.0
If we subtract 51 from 52, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 17

Let's proceed to step 6:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 40530.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
When dividing 100 by 17, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 40530.5
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.

Advancing to step 8:
When dividing 150 by 17, we get 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 40530.58
Deduct 136 from 150 and we're left 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.

Moving on to step 9:
When dividing 140 by 17, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 40530.588
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 40530.588 and a remainder of 0.0004.
