We divide 384492 by 21
Let's see how many times 21 fits into 384492.

Let's proceed to step 1:
3 divided by 21 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 21

On to step 2:
The number 21 fits into 38 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 21 away from 38, we end up with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 21

Advancing to step 3:
When dividing 174 by 21, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 168 from 174, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 21

On to step 4:
The number 21 fits into 64 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
Subtract 63 from 64 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 21

Moving on to step 5:
21 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 1830.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 21

Step 6:
21 goes into 192 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 18309.0
Subtract 189 from 192 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 18309.1
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.

Going ahead to step 8:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 18309.14
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.

Advancing to step 9:
If we divide 60 by 21, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 18309.142
If we subtract 42 from 60, we get 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 10:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 18309.1428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
If we divide 120 by 21, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 18309.14285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
21 goes into 150 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 18309.142857
Deduct 147 from 150 and we're left 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 13:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 18309.1428571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 18309.14285714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 18309.14285714 with a remainder of 6e-09.
