We're dividing 78756410 by 312 
We're looking to find how many times 312 goes into 78756410.

Going ahead to step 1:
When dividing 7 by 312, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 312

Let's proceed to step 2:
If we divide 78 by 312, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 312

Step 3:
312 goes into 787 2 times with a remainder of 163.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 624 from 787, we get 163.
Append the next digit (5) from the dividend to 163 and continue with: 1635 / 312

Let's proceed to step 4:
1635 divided by 312 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 1560 from 1635 leaves us with 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 312

Step 5:
312 goes into 756 2 times with a remainder of 132.
The next digit of our result is 2. 
Result so far: 252.0
Subtracting 624 from 756 leaves us with 132.
Append the next digit (4) from the dividend to 132 and continue with: 1324 / 312

On to step 6:
312 goes into 1324 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 2524.0
The remainder is 76 after subtracting 1248 from 1324.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 312

Going ahead to step 7:
312 goes into 761 2 times with a remainder of 137.
Use 2 as the next digit of our solution. 
Result so far: 25242.0
Subtracting 624 from 761 leaves us with 137.
Include the next digit (0) from the dividend after 137, then repeat: 1370 / 312

On to step 8:
1370 divided by 312 is 4 with a remainder of 122.
Put 4 as the next digit of the answer. 
Result so far: 252424.0
If we subtract 1248 from 1370, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 9:
1220 divided by 312 is 3 with a remainder of 284.
The next digit of our result is 3. 
Result so far: 252424.3
Subtracting 936 from 1220 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 10:
The number 312 fits into 2840 9 times, leaving a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 252424.39
Subtracting 2808 from 2840 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
312 can be fit into 320 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 252424.391
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
If we divide 80 by 312, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 252424.391
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
800 divided by 312 is 2 with a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 252424.39102
Subtract 624 from 800 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 14:
1760 divided by 312 is 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 252424.391025
If we subtract 1560 from 1760, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 15:
When dividing 2000 by 312, we get 6 with a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 252424.3910256
Subtract 1872 from 2000 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 16:
1280 divided by 312 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 252424.39102564
Subtracting 1248 from 1280 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 252424.39102564 with a balance of 3.2e-08.
