We're dividing 733283 by 21 
We want to figure out the number of times 733283 can be divided by 21.

On to step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 21

Moving on to step 2:
If we divide 73 by 21, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 63 from 73, we get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 21

Going ahead to step 3:
The number 21 fits into 103 4 times, leaving a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 84 from 103 leaves us with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 21

Going ahead to step 4:
If we divide 192 by 21, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 349.0
Deduct 189 from 192 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 21

Going ahead to step 5:
21 goes into 38 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 3491.0
Subtracting 21 from 38 leaves us with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 21

Advancing to step 6:
21 can be fit into 173 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 34918.0
The remainder is 5 after subtracting 168 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 21 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 34918.2
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 34918.23
Deduct 63 from 80 and we're left 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.

Advancing to step 9:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 34918.238
If we subtract 168 from 170, we 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.

Moving on to step 10:
If we divide 20 by 21, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 34918.238
The remainder is 20 after subtracting 0 from 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 11:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 34918.23809
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 12:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 34918.238095
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.

Let's proceed to step 13:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 34918.2380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
21 can be fit into 80 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 34918.23809523
Subtracting 63 from 80 leaves us 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.

After the division, we end up with 34918.23809523 and a remainder of 1.7e-08.
