We divide 530378 by 21
Our goal is to divide 530378 by 21.

Going ahead to step 1:
21 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 21

Advancing to step 2:
The number 21 fits into 53 2 times, leaving a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 53, we end up with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 21

Moving on to step 3:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 105 from 110, we 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:
21 goes into 53 2 times with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 252.0
Deduct 42 from 53 and we're left with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 21

Advancing to step 5:
21 can be fit into 117 5 times, resulting in a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 2525.0
If we subtract 105 from 117, we get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 21

Going ahead to step 6:
When dividing 128 by 21, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 25256.0
Subtract 126 from 128 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 25256.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 25256.09
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
When dividing 110 by 21, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 25256.095
Subtract 105 from 110 to get 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 10:
50 divided by 21 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 25256.0952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
21 goes into 80 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 25256.09523
Subtracting 63 from 80 leaves us 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.

Step 12:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 25256.095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 25256.095238
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.

Step 14:
200 divided by 21 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 25256.09523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 25256.09523809, and the remainder is 1.1e-08.
