560469 divided by 21 
Our goal is to divide 560469 by 21.

Step 1:
If we divide 5 by 21, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 21

Advancing to step 2:
21 can be fit into 56 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 42 from 56 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 21

Moving on to step 3:
21 can be fit into 140 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we subtract 126 from 140, we get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 21

Let's proceed to step 4:
The number 21 fits into 144 6 times, leaving a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 266.0
If we subtract 126 from 144, we get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 21

Step 5:
21 goes into 186 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 2668.0
If we subtract 168 from 186, we get 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 21

Moving on to step 6:
189 divided by 21 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 26689.0
Deduct 189 from 189 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.

On to step 7:
21 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26689.0
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 8:
0 divided by 21 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26689.0
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 quotient of the division is 26689.0, and the remainder is 0.0.
