80030457 ÷ 304 
We want to figure out the number of times 80030457 can be divided by 304.

Advancing to step 1:
If we divide 8 by 304, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 304

Moving on to step 2:
304 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (0) from the dividend, attach it to 80 and continue: 800 / 304

Step 3:
800 divided by 304 is 2 with a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 608 from 800 leaves us with 192.
Append the next digit (3) from the dividend to 192 and continue with: 1923 / 304

Advancing to step 4:
When dividing 1923 by 304, we get 6 with a remainder of 99.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 1824 from 1923 to get 99.
Fetch the next digit (0) from the dividend, attach it to 99 and continue: 990 / 304

Moving on to step 5:
304 goes into 990 3 times with a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 263.0
The remainder is 78 after subtracting 912 from 990.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 304

Let's proceed to step 6:
784 divided by 304 is 2 with a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 2632.0
If we subtract 608 from 784, we get 176.
Fetch the next digit (5) from the dividend, attach it to 176 and continue: 1765 / 304

Step 7:
304 can be fit into 1765 5 times, resulting in a remainder of 245.
Use 5 as the next digit of our solution. 
Result so far: 26325.0
If we take 1520 away from 1765, we end up with 245.
Grab the next digit (7) from the dividend, add it to 245, then carry on: 2457 / 304

Moving on to step 8:
When dividing 2457 by 304, we get 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 263258.0
Subtracting 2432 from 2457 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
When dividing 250 by 304, we get 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 263258.0
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
2500 divided by 304 is 8 with a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 263258.08
Subtract 2432 from 2500 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
304 goes into 680 2 times with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 263258.082
Subtracting 608 from 680 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
If we divide 720 by 304, we get 2 and a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 263258.0822
Subtract 608 from 720 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Our division results in 263258.0822 with a remaining 0.00112.
