We look at the division of 108863 by 20 
Let's see how many times 20 fits into 108863.

Step 1:
20 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 20

Advancing to step 2:
The number 20 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 20

Let's proceed to step 3:
When dividing 108 by 20, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 100 from 108 leaves us with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 20

Advancing to step 4:
When dividing 88 by 20, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 80 from 88 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 20

Advancing to step 5:
The number 20 fits into 86 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 544.0
Subtract 80 from 86 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 20

Step 6:
When dividing 63 by 20, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 5443.0
The remainder is 3 after subtracting 60 from 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 20, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 5443.1
Deduct 20 from 30 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.

Going ahead to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5443.15
The remainder is 0 after subtracting 100 from 100.
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 next digit of our result is 0. 
Result so far: 5443.15
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.

Going ahead to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5443.15
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.

After the division, we end up with 5443.15 and a remainder of 0.0.
