Let's divide 803140 by 18
Our goal is to divide 803140 by 18.

On to step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 18

On to step 2:
If we divide 80 by 18, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 72 from 80 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 18

Going ahead to step 3:
18 goes into 83 4 times with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 72 from 83, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 18

Step 4:
When dividing 111 by 18, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 446.0
If we take 108 away from 111, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 18

On to step 5:
When dividing 34 by 18, we get 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 4461.0
If we subtract 18 from 34, we get 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 18

Step 6:
When dividing 160 by 18, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 44618.0
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
The number 18 fits into 160 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 44618.8
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 44618.88
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 44618.88 and a remainder of 0.016.
