We look at the division of 12002940 by 304 
We're looking to find how many times 304 goes into 12002940.

Step 1:
The number 304 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 304

Advancing to step 2:
304 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 304

Advancing to step 3:
304 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 120 and we're left with 120.
Append the next digit (0) from the dividend to 120 and continue with: 1200 / 304

Going ahead to step 4:
304 goes into 1200 3 times with a remainder of 288.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 912 from 1200, we get 288.
Take the next digit (2) from the dividend and append it to 288, then repeat: 2882 / 304

Step 5:
2882 divided by 304 is 9 with a remainder of 146.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 146 after subtracting 2736 from 2882.
Include the next digit (9) from the dividend after 146, then repeat: 1469 / 304

Advancing to step 6:
1469 divided by 304 is 4 with a remainder of 253.
The next digit of our result is 4. 
Result so far: 394.0
The remainder is 253 after subtracting 1216 from 1469.
Bring next digit (4) of the dividend behind the 253 and repeat the process: 2534 / 304

Advancing to step 7:
When dividing 2534 by 304, we get 8 with a remainder of 102.
The next digit of our result is 8. 
Result so far: 3948.0
Subtracting 2432 from 2534 leaves us with 102.
Bring next digit (0) of the dividend behind the 102 and repeat the process: 1020 / 304

Advancing to step 8:
304 goes into 1020 3 times with a remainder of 108.
The number 3 becomes the next digit in our result. 
Result so far: 39483.0
If we take 912 away from 1020, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 9:
304 can be fit into 1080 3 times, resulting in a remainder of 168.
Write down 3 as next digit of the result. 
Result so far: 39483.3
Subtracting 912 from 1080 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 10:
304 goes into 1680 5 times with a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 39483.35
The remainder is 160 after subtracting 1520 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
304 can be fit into 1600 5 times, resulting in a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 39483.355
If we take 1520 away from 1600, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 39483.355 with a remaining 0.008.
