Let's divide 843173 by 18
We want to divide 843173 by 18.

Step 1:
8 divided by 18 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 18

Moving on to step 2:
18 goes into 84 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 72 from 84 and we're left with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 18

Moving on to step 3:
If we divide 123 by 18, we get 6 and a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we subtract 108 from 123, we get 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 18

Going ahead to step 4:
If we divide 151 by 18, we get 8 and a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 468.0
If we take 144 away from 151, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 18

Moving on to step 5:
If we divide 77 by 18, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4684.0
If we subtract 72 from 77, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 18

Let's proceed to step 6:
The number 18 fits into 53 2 times, leaving a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 46842.0
If we take 36 away from 53, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
18 goes into 170 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 46842.9
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
18 can be fit into 80 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 46842.94
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 46842.944
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 46842.944, with a leftover of 0.0008.
