278947 ÷ 78 
We want to divide 278947 by 78.

On to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 78

On to step 2:
The number 78 fits into 27 0 times, leaving a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 78

On to step 3:
When dividing 278 by 78, we get 3 with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 234 from 278 to get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 78

Advancing to step 4:
The number 78 fits into 449 5 times, leaving a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 35.0
The remainder is 59 after subtracting 390 from 449.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 78

Advancing to step 5:
78 goes into 594 7 times with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 357.0
Subtract 546 from 594 to get 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 78

On to step 6:
78 can be fit into 487 6 times, resulting in a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 3576.0
The remainder is 19 after subtracting 468 from 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
78 can be fit into 190 2 times, resulting in a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 3576.2
If we take 156 away from 190, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
340 divided by 78 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 3576.24
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 78, we get 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 3576.243
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
If we divide 460 by 78, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 3576.2435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
78 goes into 700 8 times with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 3576.24358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
When dividing 760 by 78, we get 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 3576.243589
If we subtract 702 from 760, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
580 divided by 78 is 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 3576.2435897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
78 goes into 340 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 3576.24358974
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 3576.24358974, and the remainder is 2.8e-08.
