We look at the division of 395282 by 21 
We want to divide 395282 by 21.

Step 1:
21 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 21

Advancing to step 2:
The number 21 fits into 39 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 21 from 39, we get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 21

Step 3:
185 divided by 21 is 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 17 after subtracting 168 from 185.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 21

Step 4:
The number 21 fits into 172 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 188.0
Subtracting 168 from 172 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 21

Moving on to step 5:
21 goes into 48 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 1882.0
The remainder is 6 after subtracting 42 from 48.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 21

Step 6:
62 divided by 21 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 18822.0
Subtracting 42 from 62 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.

Going ahead to step 7:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 18822.9
Subtracting 189 from 200 leaves us 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.

Step 8:
When dividing 110 by 21, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 18822.95
If we subtract 105 from 110, we 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.

Advancing to step 9:
If we divide 50 by 21, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 18822.952
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.

On to step 10:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 18822.9523
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.

Going ahead to step 11:
When dividing 170 by 21, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 18822.95238
Subtract 168 from 170 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.

Going ahead to step 12:
When dividing 20 by 21, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 18822.95238
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 13:
If we divide 200 by 21, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 18822.9523809
If we take 189 away from 200, we end up 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.

Moving on to step 14:
21 goes into 110 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 18822.95238095
Subtracting 105 from 110 leaves us 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.

After the division, we end up with 18822.95238095 and a remainder of 5e-09.
