409229 divided by 20 
Let's see how many times 20 fits into 409229.

Moving on 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
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 20

Let's proceed to step 2:
20 goes into 40 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 40 from 40, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 20

Step 3:
The number 20 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 9, we end up with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 20

Going ahead to step 4:
92 divided by 20 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
If we subtract 80 from 92, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 20

Step 5:
The number 20 fits into 122 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 2046.0
Subtract 120 from 122 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 20

Going ahead to step 6:
If we divide 29 by 20, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 20461.0
Deduct 20 from 29 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 20 fits into 90 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 20461.4
Subtract 80 from 90 to get 10.
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:
If we divide 100 by 20, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 20461.45
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.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20461.45
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.

Let's proceed to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20461.45
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.

In conclusion, the division gives 20461.45 with a balance of 0.0.
