We're dividing 993304 by 21 
Our goal is to divide 993304 by 21.

Advancing to step 1:
If we divide 9 by 21, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 21

Advancing to step 2:
21 goes into 99 4 times with a remainder of 15.
The next digit of our result is 4. 
Result so far: 4.0
If we take 84 away from 99, we end up with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 21

Step 3:
21 goes into 153 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 47.0
Subtracting 147 from 153 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 21

Going ahead to step 4:
21 can be fit into 63 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 473.0
If we subtract 63 from 63, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 21

Going ahead to step 5:
0 divided by 21 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4730.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 21

On to step 6:
When dividing 4 by 21, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 47300.0
The remainder is 4 after subtracting 0 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 21, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 47300.1
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 47300.19
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
10 divided by 21 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 47300.19
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
If we divide 100 by 21, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 47300.1904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 47300.19047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
21 goes into 130 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 47300.190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 47300.1904761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 47300.19047619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 47300.19047619 with a remainder of 1e-09.
