We divide 568430 by 20
We want to figure out the number of times 568430 can be divided by 20.

Step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 20

Moving on 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
If we take 40 away from 56, we end up with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 20

On to step 3:
The number 20 fits into 168 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 160 from 168 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 20

Step 4:
20 can be fit into 84 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 284.0
If we subtract 80 from 84, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 20

Let's proceed to step 5:
20 can be fit into 43 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2842.0
The remainder is 3 after subtracting 40 from 43.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 20

Let's proceed to step 6:
20 goes into 30 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 28421.0
Deduct 20 from 30 and we're left 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.

Advancing to step 7:
100 divided by 20 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 28421.5
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.

Moving on to step 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28421.5
If we subtract 0 from 0, we 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.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28421.5
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.

The quotient of the division is 28421.5, and the remainder is 0.0.
