560400 ÷ 20 
We want to figure out the number of times 560400 can be divided by 20.

Let's proceed to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 20

Going ahead to step 2:
The number 20 fits into 56 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 40 from 56 to get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 20

Moving on to step 3:
20 goes into 160 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 0 after subtracting 160 from 160.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 20

Advancing to step 4:
When dividing 4 by 20, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 280.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 20

Let's proceed to step 5:
If we divide 40 by 20, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2802.0
If we take 40 away from 40, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 20

On to step 6:
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: 28020.0
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.

Let's proceed to step 7:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28020.0
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.

Advancing to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28020.0
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.

After the division, we end up with 28020.0 and a remainder of 0.0.
