Let's divide 439405 by 20
Our goal is to divide 439405 by 20.

On to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 20

Advancing to step 2:
When dividing 43 by 20, we get 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 40 from 43 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 20

Advancing to step 3:
20 goes into 39 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 20 from 39, we get 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 20

On to step 4:
The number 20 fits into 194 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 219.0
If we take 180 away from 194, we end up with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 20

On to step 5:
The number 20 fits into 140 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 2197.0
Subtract 140 from 140 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 20

Going ahead to step 6:
20 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 21970.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 20, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 21970.2
The remainder is 10 after subtracting 40 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 21970.25
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.

Advancing to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21970.25
Subtract 0 from 0 to 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 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21970.25
If we take 0 away from 0, 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.

In conclusion, the division gives 21970.25 with a balance of 0.0.
