We're dividing 40263 by 20 
We want to divide 40263 by 20.

Going ahead to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 20

On to step 2:
The number 20 fits into 40 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 40 from 40 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 20

On to step 3:
If we divide 2 by 20, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 20

Moving on to step 4:
The number 20 fits into 26 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
Subtracting 20 from 26 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 20

Step 5:
63 divided by 20 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 2013.0
Subtracting 60 from 63 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 6:
30 divided by 20 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 2013.1
Subtract 20 from 30 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.

Let's proceed to step 7:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2013.15
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.

Let's proceed to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2013.15
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.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2013.15
Subtracting 0 from 0 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.

Our division results in 2013.15 with a remaining 0.0.
