300812 ÷ 80 
We want to divide 300812 by 80.

Let's proceed to step 1:
80 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 80

On to step 2:
30 divided by 80 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 80

Advancing to step 3:
When dividing 300 by 80, we get 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 240 from 300, we get 60.
Append the next digit (8) from the dividend to 60 and continue with: 608 / 80

Step 4:
If we divide 608 by 80, we get 7 and a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 560 from 608 leaves us with 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 80

Going ahead to step 5:
The number 80 fits into 481 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 376.0
Subtract 480 from 481 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 80

Going ahead to step 6:
80 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 3760.0
Deduct 0 from 12 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
When dividing 120 by 80, we get 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 3760.1
Subtracting 80 from 120 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3760.15
If we take 400 away from 400, 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.

Let's proceed to step 9:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3760.15
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.

Moving on to step 10:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3760.15
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.

The final result is 3760.15 with a remainder of 0.0.
