575507 divided by 20 
Let's see how many times 20 fits into 575507.

Moving on to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 20

Going ahead to step 2:
57 divided by 20 is 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 40 from 57 leaves us with 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 20

Let's proceed to step 3:
When dividing 175 by 20, we get 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 15 after subtracting 160 from 175.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 20

Step 4:
20 goes into 155 7 times with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 287.0
The remainder is 15 after subtracting 140 from 155.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 20

Moving on 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: 2877.0
Deduct 140 from 150 and we're left with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 20

Moving on to step 6:
20 can be fit into 107 5 times, resulting in a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 28775.0
If we subtract 100 from 107, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 20, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 28775.3
Subtract 60 from 70 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.

Going ahead to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 28775.35
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.

Step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28775.35
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.

Step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 28775.35
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.

The final outcome is 28775.35, with a leftover of 0.0.
