We look at the division of 276436 by 80 
Our goal is to divide 276436 by 80.

On to step 1:
2 divided by 80 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 80

Step 2:
The number 80 fits into 27 0 times, leaving a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 80

On to step 3:
80 can be fit into 276 3 times, resulting in a remainder of 36.
The next digit of our result is 3. 
Result so far: 3.0
If we take 240 away from 276, we end up with 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 80

Step 4:
364 divided by 80 is 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtract 320 from 364 to get 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 80

Step 5:
80 goes into 443 5 times with a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 345.0
If we subtract 400 from 443, we get 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 80

Let's proceed to step 6:
80 goes into 436 5 times with a remainder of 36.
The next digit of our result is 5. 
Result so far: 3455.0
Subtract 400 from 436 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
80 goes into 360 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 3455.4
If we take 320 away from 360, we end up 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.

Moving on to step 8:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3455.45
Subtracting 400 from 400 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.

Step 9:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3455.45
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.

Advancing to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3455.45
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 quotient of the division is 3455.45, and the remainder is 0.0.
