530384 divided by 21 
Let's see how many times 21 fits into 530384.

Advancing to step 1:
21 goes into 5 0 times with 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.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 21

Moving on to step 2:
21 goes into 53 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 11 after subtracting 42 from 53.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 21

Let's proceed to step 3:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 105 from 110 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 21

Let's proceed to step 4:
If we divide 53 by 21, we get 2 and a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 252.0
The remainder is 11 after subtracting 42 from 53.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 21

Advancing to step 5:
21 goes into 118 5 times with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 2525.0
Subtract 105 from 118 to get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 21

Going ahead to step 6:
When dividing 134 by 21, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 25256.0
Subtract 126 from 134 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
80 divided by 21 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 25256.3
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 25256.38
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
When dividing 20 by 21, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 25256.38
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
200 divided by 21 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 25256.3809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 25256.38095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 25256.380952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
21 goes into 80 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 25256.3809523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
If we divide 170 by 21, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 25256.38095238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 25256.38095238 with a balance of 2e-09.
