We're dividing 12279856 by 344 
We want to divide 12279856 by 344.

Moving on to step 1:
The number 344 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 344

Step 2:
344 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 344

Advancing to step 3:
344 goes into 122 0 times with a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 122, we get 122.
Include the next digit (7) from the dividend after 122, then repeat: 1227 / 344

Going ahead to step 4:
The number 344 fits into 1227 3 times, leaving a remainder of 195.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1032 from 1227, we get 195.
Bring next digit (9) of the dividend behind the 195 and repeat the process: 1959 / 344

Going ahead to step 5:
344 can be fit into 1959 5 times, resulting in a remainder of 239.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtracting 1720 from 1959 leaves us with 239.
Grab the next digit (8) from the dividend, add it to 239, then carry on: 2398 / 344

Moving on to step 6:
When dividing 2398 by 344, we get 6 with a remainder of 334.
Put 6 as the next digit of the answer. 
Result so far: 356.0
Deduct 2064 from 2398 and we're left with 334.
Take the next digit (5) from the dividend and append it to 334, then repeat: 3345 / 344

Step 7:
344 goes into 3345 9 times with a remainder of 249.
The next digit of our result is 9. 
Result so far: 3569.0
If we take 3096 away from 3345, we end up with 249.
Grab the next digit (6) from the dividend, add it to 249, then carry on: 2496 / 344

Let's proceed to step 8:
2496 divided by 344 is 7 with a remainder of 88.
The number 7 becomes the next digit in our result. 
Result so far: 35697.0
Subtract 2408 from 2496 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 9:
344 goes into 880 2 times with a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 35697.2
If we subtract 688 from 880, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 10:
344 can be fit into 1920 5 times, resulting in a remainder of 200.
The next digit of our result is 5. 
Result so far: 35697.25
The remainder is 200 after subtracting 1720 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
If we divide 2000 by 344, we get 5 and a remainder of 280.
The next digit of our result is 5. 
Result so far: 35697.255
Subtracting 1720 from 2000 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 35697.255 with a remainder of 0.028.
