204587 divided by 17 
The aim is to understand the frequency of 17 in 204587.

Let's proceed to step 1:
When dividing 2 by 17, we get 0 with 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.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 17

Advancing to step 2:
When dividing 20 by 17, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 17 from 20, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 17

Moving on to step 3:
34 divided by 17 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 34 from 34, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 17

Let's proceed to step 4:
If we divide 5 by 17, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
If we subtract 0 from 5, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 17

Let's proceed to step 5:
17 can be fit into 58 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 1203.0
If we subtract 51 from 58, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 17

Advancing to step 6:
17 can be fit into 77 4 times, resulting in a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 12034.0
Subtracting 68 from 77 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 17, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12034.5
The remainder is 5 after subtracting 85 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 17 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12034.52
Subtract 34 from 50 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.

Advancing to step 9:
17 can be fit into 160 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 12034.529
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
17 goes into 70 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 12034.5294
Deduct 68 from 70 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
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: 12034.52941
Subtracting 17 from 20 leaves us 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.

Going ahead to step 12:
30 divided by 17 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 12034.529411
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 result is 12034.529411 with a remainder of 1.3e-06.
