Let's divide 578565 by 20
Let's see how many times 20 fits into 578565.

Moving on to step 1:
20 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 20

Going ahead to step 2:
20 goes into 57 2 times with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 40 from 57, we get 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 20

Advancing to step 3:
The number 20 fits into 178 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 160 from 178 to get 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 20

Advancing to step 4:
When dividing 185 by 20, we get 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
If we take 180 away from 185, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 20

Step 5:
When dividing 56 by 20, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 2892.0
Deduct 40 from 56 and we're left with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 20

Moving on to step 6:
The number 20 fits into 165 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 28928.0
If we subtract 160 from 165, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 20, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 28928.2
Subtracting 40 from 50 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.

Step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 28928.25
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28928.25
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:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28928.25
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.

After the division, we end up with 28928.25 and a remainder of 0.0.
