We divide 304980 by 78
We're looking to find how many times 78 goes into 304980.

On to step 1:
3 divided by 78 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 78

Moving on to step 2:
The number 78 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 78

Step 3:
78 goes into 304 3 times with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 234 from 304, we get 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 78

Going ahead to step 4:
78 goes into 709 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 7 after subtracting 702 from 709.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 78

On to step 5:
78 goes into 78 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 391.0
If we subtract 78 from 78, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 78

On to step 6:
78 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3910.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
78 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3910.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 78 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3910.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 3910.0 with a remainder of 0.0.
