We look at the division of 302833 by 21 
We're looking to find how many times 21 goes into 302833.

Going ahead to step 1:
3 divided by 21 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 21

Going ahead to step 2:
When dividing 30 by 21, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 21 from 30, we get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 21

Advancing to step 3:
If we divide 92 by 21, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 84 from 92 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 21

Let's proceed to step 4:
21 goes into 88 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 144.0
Subtracting 84 from 88 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 21

Going ahead to step 5:
21 goes into 43 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 1442.0
Subtract 42 from 43 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 21

On to step 6:
21 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 14420.0
Subtracting 0 from 13 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.

Advancing to step 7:
If we divide 130 by 21, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 14420.6
If we take 126 away from 130, we end up with 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 8:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 14420.61
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
If we divide 190 by 21, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 14420.619
If we take 189 away from 190, we end up 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.

Going ahead to step 10:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 14420.619
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 14420.61904
Subtracting 84 from 100 leaves us 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.

Moving on to step 12:
When dividing 160 by 21, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 14420.619047
Deduct 147 from 160 and we're left 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.

Let's proceed to step 13:
If we divide 130 by 21, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 14420.6190476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 14420.61904761
Deduct 21 from 40 and we're left 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.

The final result is 14420.61904761 with a remainder of 1.9e-08.
