We divide 204286 by 18
The aim is to understand the frequency of 18 in 204286.

Let's proceed to step 1:
When dividing 2 by 18, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 18

Let's proceed to step 2:
If we divide 20 by 18, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 18 from 20, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 18

Advancing to step 3:
18 goes into 24 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 18 from 24, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 18

On to step 4:
62 divided by 18 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Subtracting 54 from 62 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 18

Let's proceed to step 5:
If we divide 88 by 18, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1134.0
If we subtract 72 from 88, we get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 18

On to step 6:
18 can be fit into 166 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 11349.0
If we take 162 away from 166, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
18 goes into 40 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 11349.2
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
If we divide 40 by 18, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 11349.22
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 11349.22, with a leftover of 0.004.
