We're dividing 573113 by 20 
Let's see how many times 20 fits into 573113.

Step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 20

Step 2:
If we divide 57 by 20, we get 2 and a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 40 from 57, we get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 20

Moving on to step 3:
20 can be fit into 173 8 times, resulting in a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 160 from 173 leaves us with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 20

Moving on to step 4:
When dividing 131 by 20, we get 6 with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 286.0
If we subtract 120 from 131, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 20

On to step 5:
111 divided by 20 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 2865.0
The remainder is 11 after subtracting 100 from 111.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 20

Advancing to step 6:
The number 20 fits into 113 5 times, leaving a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 28655.0
The remainder is 13 after subtracting 100 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
20 can be fit into 130 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 28655.6
If we take 120 away from 130, we end up 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.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 28655.65
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.

On to step 9:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28655.65
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.

On to step 10:
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: 28655.65
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 28655.65 with a remaining 0.0.
