We look at the division of 312011 by 18 
We're looking to find how many times 18 goes into 312011.

Let's proceed to step 1:
The number 18 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 18

Advancing to step 2:
18 can be fit into 31 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 18 from 31 leaves us with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 18

Let's proceed to step 3:
18 goes into 132 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 126 from 132 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 18

Moving on to step 4:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Deduct 54 from 60 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 18

On to step 5:
61 divided by 18 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 1733.0
If we take 54 away from 61, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 18

Advancing to step 6:
When dividing 71 by 18, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 17333.0
Subtracting 54 from 71 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
When dividing 170 by 18, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 17333.9
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
When dividing 80 by 18, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 17333.94
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
80 divided by 18 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 17333.944
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 17333.944, with a leftover of 0.0008.
