308259 ÷ 80 
Our goal is to divide 308259 by 80.

Moving on to step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 80

Moving on to step 2:
30 divided by 80 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 80

Let's proceed to step 3:
If we divide 308 by 80, we get 3 and a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 68 after subtracting 240 from 308.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 80

Advancing to step 4:
682 divided by 80 is 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 640 from 682 leaves us with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 80

Going ahead to step 5:
425 divided by 80 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 385.0
The remainder is 25 after subtracting 400 from 425.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 80

Let's proceed to step 6:
When dividing 259 by 80, we get 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3853.0
The remainder is 19 after subtracting 240 from 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
80 can be fit into 190 2 times, resulting in a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 3853.2
If we subtract 160 from 190, we 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.

Let's proceed to step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
The next digit of our result is 3. 
Result so far: 3853.23
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.

Going ahead to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 3853.237
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:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 3853.2375
Deduct 400 from 400 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.

Step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3853.2375
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 12:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3853.2375
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.

The final result is 3853.2375 with a remainder of 0.0.
