571506 ÷ 20 
Our goal is to divide 571506 by 20.

Let's proceed to step 1:
20 can be fit into 5 0 times, resulting in 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.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

On to step 2:
20 can be fit into 57 2 times, resulting in a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 17 after subtracting 40 from 57.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 20

Step 3:
The number 20 fits into 171 8 times, leaving a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 160 from 171 to get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 20

Advancing to step 4:
20 can be fit into 115 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 285.0
If we take 100 away from 115, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 20

Going ahead to step 5:
20 can be fit into 150 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 2857.0
If we subtract 140 from 150, we get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 20

Step 6:
20 goes into 106 5 times with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 28575.0
If we subtract 100 from 106, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
20 goes into 60 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 28575.3
Deduct 60 from 60 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.

Step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28575.3
The remainder is 0 after subtracting 0 from 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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28575.3
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.

The final outcome is 28575.3, with a leftover of 0.0.
