We look at the division of 431361 by 20 
We're looking to find how many times 20 goes into 431361.

Moving on to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 20

Step 2:
20 can be fit into 43 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 40 from 43 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 20

Let's proceed to step 3:
31 divided by 20 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 21.0
If we take 20 away from 31, we end up with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 20

Advancing to step 4:
When dividing 113 by 20, we get 5 with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 215.0
The remainder is 13 after subtracting 100 from 113.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 20

Step 5:
20 goes into 136 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 2156.0
The remainder is 16 after subtracting 120 from 136.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 20

Moving on to step 6:
When dividing 161 by 20, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 21568.0
If we subtract 160 from 161, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 20, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 21568.0
If we subtract 0 from 10, we 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.

Advancing to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 21568.05
Subtracting 100 from 100 leaves us 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.

On 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: 21568.05
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.

On to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21568.05
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 21568.05 with a balance of 0.0.
