We look at the division of 304280 by 99 
Let's see how many times 99 fits into 304280.

Let's proceed to step 1:
99 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 99

Moving on to step 2:
The number 99 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 99

Advancing to step 3:
When dividing 304 by 99, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 297 from 304 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 99

Moving on to step 4:
99 goes into 72 0 times with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 72, we get 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 99

Moving on to step 5:
The number 99 fits into 728 7 times, leaving a remainder of 35.
The next digit of our result is 7. 
Result so far: 307.0
Subtract 693 from 728 to get 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 99

Advancing to step 6:
99 can be fit into 350 3 times, resulting in a remainder of 53.
The next digit of our result is 3. 
Result so far: 3073.0
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
The number 99 fits into 530 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 3073.5
If we take 495 away from 530, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
If we divide 350 by 99, we get 3 and a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 3073.53
The remainder is 53 after subtracting 297 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
When dividing 530 by 99, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 3073.535
If we take 495 away from 530, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
When dividing 350 by 99, we get 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 3073.5353
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 11:
99 can be fit into 530 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 3073.53535
Subtract 495 from 530 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
350 divided by 99 is 3 with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 3073.535353
If we subtract 297 from 350, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 13:
99 can be fit into 530 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 3073.5353535
Subtracting 495 from 530 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
When dividing 350 by 99, we get 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 3073.53535353
Subtract 297 from 350 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final result is 3073.53535353 with a remainder of 5.3e-08.
