39830 ÷ 20 
Our goal is to divide 39830 by 20.

Let's proceed to step 1:
When dividing 3 by 20, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 20

Going ahead to step 2:
If we divide 39 by 20, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 20 away from 39, we end up with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 20

Step 3:
20 can be fit into 198 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 180 away from 198, we end up with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 20

Moving on to step 4:
20 can be fit into 183 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 199.0
If we take 180 away from 183, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 20

Step 5:
When dividing 30 by 20, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1991.0
Subtracting 20 from 30 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1991.5
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1991.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1991.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1991.5, with a leftover of 0.0.
