559622 divided by 21 
We're looking to find how many times 21 goes into 559622.

Going ahead to step 1:
The number 21 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 21

On to step 2:
When dividing 55 by 21, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 42 from 55 to get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 21

Moving on to step 3:
The number 21 fits into 139 6 times, leaving a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 126 from 139 leaves us with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 21

Let's proceed to step 4:
136 divided by 21 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 266.0
If we take 126 away from 136, we end up with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 21

Going ahead to step 5:
21 can be fit into 102 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 2664.0
Subtracting 84 from 102 leaves us with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 21

Moving on to step 6:
The number 21 fits into 182 8 times, leaving a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 26648.0
If we take 168 away from 182, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 26648.6
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
140 divided by 21 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 26648.66
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 26648.66 and a remainder of 0.014.
