Let's divide 431063 by 20
We want to figure out the number of times 431063 can be divided by 20.

Going ahead 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
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 20

Going ahead to step 2:
When dividing 43 by 20, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 40 from 43 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 20

Going ahead to step 3:
20 can be fit into 31 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 20 from 31, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 20

Going ahead to step 4:
20 can be fit into 110 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
If we subtract 100 from 110, we get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 20

Going ahead to step 5:
When dividing 106 by 20, we get 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 2155.0
If we take 100 away from 106, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 20

Advancing to step 6:
When dividing 63 by 20, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 21553.0
If we subtract 60 from 63, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
20 goes into 30 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 21553.1
The remainder is 10 after subtracting 20 from 30.
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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 21553.15
Deduct 100 from 100 and we're left 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 9:
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: 21553.15
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.

Moving on to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21553.15
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.

The quotient of the division is 21553.15, and the remainder is 0.0.
