We're dividing 287769 by 17 
The aim is to understand the frequency of 17 in 287769.

On to step 1:
2 divided by 17 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 17

Moving on to step 2:
17 can be fit into 28 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 17 from 28, we get 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 17

Let's proceed to step 3:
The number 17 fits into 117 6 times, leaving a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 102 from 117, we get 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 17

Going ahead to step 4:
When dividing 157 by 17, we get 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Subtracting 153 from 157 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 17

On to step 5:
17 can be fit into 46 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 1692.0
Deduct 34 from 46 and we're left with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 17

Moving on to step 6:
When dividing 129 by 17, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 16927.0
Subtract 119 from 129 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.

On to step 7:
When dividing 100 by 17, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 16927.5
Subtracting 85 from 100 leaves us with 15.
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 8:
17 can be fit into 150 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 16927.58
The remainder is 14 after subtracting 136 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
If we divide 140 by 17, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 16927.588
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.

In conclusion, the division gives 16927.588 with a balance of 0.0004.
