115803 divided by 20 
Our goal is to divide 115803 by 20.

On to step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 20

Going ahead to step 2:
The number 20 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 20

Moving on to step 3:
115 divided by 20 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 15 after subtracting 100 from 115.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 20

Advancing to step 4:
When dividing 158 by 20, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtract 140 from 158 to get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 20

Let's proceed to step 5:
When dividing 180 by 20, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 579.0
Deduct 180 from 180 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 20

Moving on to step 6:
20 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 5790.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 20 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 5790.1
Subtracting 20 from 30 leaves us 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.

Moving on to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 5790.15
Subtract 100 from 100 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.

Advancing to step 9:
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: 5790.15
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.

On to step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5790.15
Deduct 0 from 0 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.

The final result is 5790.15 with a remainder of 0.0.
