530583 divided by 21 
We're looking to find how many times 21 goes into 530583.

Step 1:
21 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 21

Step 2:
When dividing 53 by 21, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 42 from 53 to get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 21

Going ahead to step 3:
110 divided by 21 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 5 after subtracting 105 from 110.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 21

Let's proceed to step 4:
21 goes into 55 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 252.0
If we subtract 42 from 55, we get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 21

On to step 5:
21 can be fit into 138 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 2526.0
Deduct 126 from 138 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 21

Let's proceed to step 6:
21 goes into 123 5 times with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 25265.0
The remainder is 18 after subtracting 105 from 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
21 goes into 180 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 25265.8
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 21, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 25265.85
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
21 goes into 150 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 25265.857
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
21 goes into 30 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 25265.8571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
When dividing 90 by 21, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 25265.85714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 25265.857142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 25265.8571428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 25265.85714285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 25265.85714285 with a balance of 1.5e-08.
