304872 ÷ 80 
We want to figure out the number of times 304872 can be divided by 80.

Advancing to step 1:
If we divide 3 by 80, we get 0 and 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.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 80

On to step 2:
If we divide 30 by 80, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our 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 / 80

Let's proceed to step 3:
The number 80 fits into 304 3 times, leaving a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 240 away from 304, we end up with 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 80

Going ahead to step 4:
648 divided by 80 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 640 from 648, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 80

On to step 5:
The number 80 fits into 87 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 381.0
If we take 80 away from 87, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 80

Going ahead to step 6:
If we divide 72 by 80, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 3810.0
If we subtract 0 from 72, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 7:
The number 80 fits into 720 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 3810.9
Subtracting 720 from 720 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.

Let's proceed to step 8:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3810.9
If we subtract 0 from 0, we 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 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3810.9
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 3810.9 with a balance of 0.0.
