We're dividing 809831 by 18 
We want to divide 809831 by 18.

Step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 18

Step 2:
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: 4.0
If we subtract 72 from 80, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 18

On to step 3:
89 divided by 18 is 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 44.0
The remainder is 17 after subtracting 72 from 89.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 18

Going ahead to step 4:
When dividing 178 by 18, we get 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 449.0
If we subtract 162 from 178, we get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 18

Step 5:
18 can be fit into 163 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 4499.0
If we subtract 162 from 163, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 18

Step 6:
18 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 44990.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
If we divide 110 by 18, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 44990.6
Deduct 108 from 110 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.

Moving on to step 8:
When dividing 20 by 18, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 44990.61
Subtracting 18 from 20 leaves us 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 9:
20 divided by 18 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 44990.611
Deduct 18 from 20 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.

After the division, we end up with 44990.611 and a remainder of 0.0002.
