We're dividing 79394878 by 278 
Our goal is to divide 79394878 by 278.

Step 1:
If we divide 7 by 278, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 278

On to step 2:
79 divided by 278 is 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Bring next digit (3) of the dividend behind the 79 and repeat the process: 793 / 278

Moving on to step 3:
278 can be fit into 793 2 times, resulting in a remainder of 237.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 556 from 793 leaves us with 237.
Include the next digit (9) from the dividend after 237, then repeat: 2379 / 278

Step 4:
The number 278 fits into 2379 8 times, leaving a remainder of 155.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 2224 away from 2379, we end up with 155.
Include the next digit (4) from the dividend after 155, then repeat: 1554 / 278

Let's proceed to step 5:
1554 divided by 278 is 5 with a remainder of 164.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
The remainder is 164 after subtracting 1390 from 1554.
Include the next digit (8) from the dividend after 164, then repeat: 1648 / 278

Step 6:
278 goes into 1648 5 times with a remainder of 258.
Put 5 as the next digit of the answer. 
Result so far: 2855.0
Subtract 1390 from 1648 to get 258.
Bring next digit (7) of the dividend behind the 258 and repeat the process: 2587 / 278

Advancing to step 7:
When dividing 2587 by 278, we get 9 with a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 28559.0
Deduct 2502 from 2587 and we're left with 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 278

Advancing to step 8:
278 can be fit into 858 3 times, resulting in a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 285593.0
If we subtract 834 from 858, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 278, we get 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 285593.0
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
The number 278 fits into 2400 8 times, leaving a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 285593.08
Subtracting 2224 from 2400 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 11:
278 can be fit into 1760 6 times, resulting in a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 285593.086
Subtract 1668 from 1760 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 12:
The number 278 fits into 920 3 times, leaving a remainder of 86.
The next digit of our result is 3. 
Result so far: 285593.0863
Subtracting 834 from 920 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 13:
278 goes into 860 3 times with a remainder of 26.
The next digit of our result is 3. 
Result so far: 285593.08633
If we subtract 834 from 860, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 285593.08633 with a balance of 2.6e-05.
