We're dividing 300307 by 80 
We want to figure out the number of times 300307 can be divided by 80.

Step 1:
80 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 80

Let's proceed to step 2:
80 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 80

On to step 3:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 240 from 300 and we're left with 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 80

Advancing to step 4:
If we divide 603 by 80, we get 7 and a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 43 after subtracting 560 from 603.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 80

Moving on to step 5:
When dividing 430 by 80, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
Subtracting 400 from 430 leaves us with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 80

Let's proceed to step 6:
307 divided by 80 is 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 3753.0
The remainder is 67 after subtracting 240 from 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
When dividing 670 by 80, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 3753.8
Subtract 640 from 670 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
80 goes into 300 3 times with a remainder of 60.
The next digit of our result is 3. 
Result so far: 3753.83
Deduct 240 from 300 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
80 goes into 600 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 3753.837
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3753.8375
If we subtract 400 from 400, 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.

Moving on to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3753.8375
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.

Moving on to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3753.8375
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.

In conclusion, the division gives 3753.8375 with a balance of 0.0.
