285218 divided by 17 
The aim is to understand the frequency of 17 in 285218.

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.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 17

Step 2:
17 can be fit into 28 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 17 from 28 leaves us with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 17

Advancing to step 3:
When dividing 115 by 17, we get 6 with a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 102 from 115 to get 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 17

Advancing to step 4:
17 can be fit into 132 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 167.0
If we subtract 119 from 132, we get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 17

Moving on to step 5:
17 can be fit into 131 7 times, resulting in a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 1677.0
Subtracting 119 from 131 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 17

Advancing to step 6:
128 divided by 17 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 16777.0
Subtract 119 from 128 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 17 fits into 90 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 16777.5
Subtracting 85 from 90 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
50 divided by 17 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 16777.52
Deduct 34 from 50 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
17 goes into 160 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 16777.529
Subtracting 153 from 160 leaves us 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.

Let's proceed to step 10:
17 goes into 70 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 16777.5294
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:
20 divided by 17 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 16777.52941
The remainder is 3 after subtracting 17 from 20.
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:
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: 16777.529411
The remainder is 13 after subtracting 17 from 30.
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 16777.529411 with a remainder of 1.3e-06.
