We're dividing 820149 by 18 
Let's see how many times 18 fits into 820149.

Step 1:
8 divided by 18 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 18

On to step 2:
82 divided by 18 is 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 72 from 82 and we're left with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 18

On to step 3:
When dividing 100 by 18, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtract 90 from 100 to get 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 18

Going ahead to step 4:
When dividing 101 by 18, we get 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 455.0
If we subtract 90 from 101, we get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 18

Advancing to step 5:
18 can be fit into 114 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 4556.0
Deduct 108 from 114 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 18

On to step 6:
If we divide 69 by 18, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 45563.0
Subtracting 54 from 69 leaves us 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.

Moving on to step 7:
18 goes into 150 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 45563.8
Subtracting 144 from 150 leaves us 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.

Step 8:
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: 45563.83
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 18 fits into 60 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 45563.833
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.

The final outcome is 45563.833, with a leftover of 0.0006.
