We look at the division of 802245 by 18 
Our goal is to divide 802245 by 18.

Step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 18

Going ahead to step 2:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 72 from 80, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 18

Advancing to step 3:
If we divide 82 by 18, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtract 72 from 82 to get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 18

Step 4:
18 goes into 102 5 times with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 445.0
The remainder is 12 after subtracting 90 from 102.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 18

Step 5:
18 goes into 124 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 4456.0
Subtract 108 from 124 to get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 18

Let's proceed to step 6:
The number 18 fits into 165 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 44569.0
Subtract 162 from 165 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
18 goes into 30 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 44569.1
The remainder is 12 after subtracting 18 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
18 goes into 120 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 44569.16
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 18 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 44569.166
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 44569.166 with a remaining 0.0012.
