287528 divided by 17 
The aim is to understand the frequency of 17 in 287528.

Going ahead to step 1:
2 divided by 17 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 17

Moving on to step 2:
17 goes into 28 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 17 from 28 leaves us with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 17

Going ahead to step 3:
If we divide 117 by 17, we get 6 and a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 102 from 117 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 17

On to step 4:
17 can be fit into 155 9 times, resulting in a remainder of 2.
The next digit of our result is 9. 
Result so far: 169.0
Subtracting 153 from 155 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 17

Moving on to step 5:
When dividing 22 by 17, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1691.0
Deduct 17 from 22 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 17

Let's proceed to step 6:
If we divide 58 by 17, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 16913.0
If we take 51 away from 58, 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 7:
70 divided by 17 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 16913.4
If we subtract 68 from 70, we 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.

On to step 8:
17 can be fit into 20 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 16913.41
If we subtract 17 from 20, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
When dividing 30 by 17, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 16913.411
Deduct 17 from 30 and we're left with 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 outcome is 16913.411, with a leftover of 0.0013.
