Let's divide 78915276 by 257
Let's see how many times 257 fits into 78915276.

Going ahead to step 1:
The number 257 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 257

On to step 2:
257 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 257

Going ahead to step 3:
If we divide 789 by 257, we get 3 and a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 771 from 789 and we're left with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 257

Going ahead to step 4:
257 can be fit into 181 0 times, resulting in a remainder of 181.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 181, we get 181.
Bring next digit (5) of the dividend behind the 181 and repeat the process: 1815 / 257

Step 5:
The number 257 fits into 1815 7 times, leaving a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 307.0
If we subtract 1799 from 1815, we get 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 257

Going ahead to step 6:
When dividing 162 by 257, we get 0 with a remainder of 162.
Use 0 as the next digit of our solution. 
Result so far: 3070.0
If we subtract 0 from 162, we get 162.
Bring next digit (7) of the dividend behind the 162 and repeat the process: 1627 / 257

Let's proceed to step 7:
1627 divided by 257 is 6 with a remainder of 85.
Put 6 as the next digit of the answer. 
Result so far: 30706.0
If we subtract 1542 from 1627, we get 85.
Fetch the next digit (6) from the dividend, attach it to 85 and continue: 856 / 257

Step 8:
257 goes into 856 3 times with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 307063.0
If we subtract 771 from 856, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 9:
When dividing 850 by 257, we get 3 with a remainder of 79.
The next digit of our result is 3. 
Result so far: 307063.3
Subtract 771 from 850 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 10:
790 divided by 257 is 3 with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 307063.33
The remainder is 19 after subtracting 771 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 307063.33 with a balance of 0.019.
