We're dividing 83940 by 18 
Our goal is to divide 83940 by 18.

Let's proceed to step 1:
If we divide 8 by 18, we get 0 and 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.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 18

Step 2:
18 can be fit into 83 4 times, resulting in a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 72 from 83 to get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 18

Let's proceed to step 3:
When dividing 119 by 18, we get 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we subtract 108 from 119, we get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 18

Step 4:
114 divided by 18 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 466.0
If we subtract 108 from 114, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 18

Moving on to step 5:
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: 4663.0
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.

Going ahead to step 6:
When dividing 60 by 18, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 4663.3
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.

Going ahead to step 7:
18 goes into 60 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 4663.33
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.

The final result is 4663.33 with a remainder of 0.006.
