We divide 809372 by 18
We're looking to find how many times 18 goes into 809372.

Moving on to step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 18

Let's proceed to step 2:
If we divide 80 by 18, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 72 from 80 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 18

Going ahead to step 3:
89 divided by 18 is 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtracting 72 from 89 leaves us with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 18

Moving on to step 4:
If we divide 173 by 18, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 449.0
The remainder is 11 after subtracting 162 from 173.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 18

Step 5:
When dividing 117 by 18, we get 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 4496.0
If we take 108 away from 117, we end up with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 18

Let's proceed to step 6:
18 goes into 92 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 44965.0
If we subtract 90 from 92, we get 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 7:
18 can be fit into 20 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 44965.1
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 18 fits into 20 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 44965.11
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.

The final outcome is 44965.11, with a leftover of 0.002.
