2 divided by 18 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 18

Moving on to step 2:
20 divided by 18 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 18 from 20 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 18

Going ahead to step 3:
The number 18 fits into 29 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 18 away from 29, we end up with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 18

Advancing to step 5:
When dividing 48 by 18, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 1162.0
Subtract 36 from 48 to get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 18

On to step 6:
18 can be fit into 123 6 times, resulting in a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 11626.0
Deduct 108 from 123 and we're left 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.

On to step 7:
When dividing 150 by 18, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 11626.8
The remainder is 6 after subtracting 144 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
The number 18 fits into 60 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 11626.83
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 11626.833
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 11626.833 and a remainder of 0.0006.
