413899 ÷ 20 
Our goal is to divide 413899 by 20.

On to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 20

Moving on to step 2:
When dividing 41 by 20, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 40 away from 41, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 20

Going ahead to step 3:
20 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 20

On to step 4:
138 divided by 20 is 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 206.0
If we take 120 away from 138, we end up with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 20

On to step 5:
189 divided by 20 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 2069.0
If we subtract 180 from 189, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 20

Going ahead to step 6:
99 divided by 20 is 4 with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 20694.0
If we subtract 80 from 99, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 20694.9
Deduct 180 from 190 and we're left 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.

Let's proceed to 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: 20694.95
If we subtract 100 from 100, 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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20694.95
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.

Moving on to step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20694.95
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 20694.95 with a balance of 0.0.
