We look at the division of 382193 by 21 
Let's see how many times 21 fits into 382193.

Going ahead to step 1:
21 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 21

Advancing to step 2:
If we divide 38 by 21, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 21 from 38 and we're left with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 21

Advancing to step 3:
The number 21 fits into 172 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 168 from 172, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 21

Advancing to step 4:
The number 21 fits into 41 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
The remainder is 20 after subtracting 21 from 41.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 21

Step 5:
21 goes into 209 9 times with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 1819.0
If we subtract 189 from 209, we get 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 21

Step 6:
If we divide 203 by 21, we get 9 and a remainder of 14.
The next digit of our result is 9. 
Result so far: 18199.0
Subtract 189 from 203 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
21 goes into 140 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 18199.6
Deduct 126 from 140 and we're left 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.

Advancing to step 8:
21 goes into 140 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 18199.66
If we subtract 126 from 140, we get 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 18199.66 and a remainder of 0.014.
