278274 ÷ 39 
We want to divide 278274 by 39.

Step 1:
When dividing 2 by 39, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 39

Going ahead to step 2:
The number 39 fits into 27 0 times, leaving a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 39

Going ahead to step 3:
39 goes into 278 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 273 from 278 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 39

Let's proceed to step 4:
The number 39 fits into 52 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we subtract 39 from 52, we get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 39

Advancing to step 5:
39 goes into 137 3 times with a remainder of 20.
The next digit of our result is 3. 
Result so far: 713.0
If we take 117 away from 137, we end up with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 39

Moving on to step 6:
204 divided by 39 is 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 7135.0
If we subtract 195 from 204, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 39 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 7135.2
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
When dividing 120 by 39, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 7135.23
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7135.23
If we subtract 0 from 30, 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 10:
39 goes into 300 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 7135.2307
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
270 divided by 39 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 7135.23076
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
39 can be fit into 360 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 7135.230769
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
39 goes into 90 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 7135.2307692
Deduct 78 from 90 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 14:
39 goes into 120 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 7135.23076923
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 7135.23076923, with a leftover of 3e-09.
