439833 divided by 20 
Our goal is to divide 439833 by 20.

Let's proceed to step 1:
4 divided by 20 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 20

Advancing to step 2:
The number 20 fits into 43 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 3 after subtracting 40 from 43.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 20

Going ahead to step 3:
When dividing 39 by 20, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 20 from 39 and we're left with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 20

Advancing to step 4:
20 can be fit into 198 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 219.0
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

Step 5:
When dividing 183 by 20, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 2199.0
If we subtract 180 from 183, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 20

Advancing to step 6:
20 can be fit into 33 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 21991.0
If we take 20 away from 33, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
20 goes into 130 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 21991.6
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 21991.65
If we take 100 away from 100, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21991.65
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.

Advancing to step 10:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21991.65
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.

Our division results in 21991.65 with a remaining 0.0.
