Let's divide 518536 by 78
We're looking to find how many times 78 goes into 518536.

Moving on to step 1:
78 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 78

Going ahead to step 2:
78 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 78

On to step 3:
If we divide 518 by 78, we get 6 and a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 468 from 518 and we're left with 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 78

Moving on to step 4:
The number 78 fits into 505 6 times, leaving a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we subtract 468 from 505, we get 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 78

Step 5:
The number 78 fits into 373 4 times, leaving a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 664.0
Subtracting 312 from 373 leaves us with 61.
Include the next digit (6) from the dividend after 61, then repeat: 616 / 78

Moving on to step 6:
If we divide 616 by 78, we get 7 and a remainder of 70.
The next digit of our result is 7. 
Result so far: 6647.0
If we take 546 away from 616, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
The number 78 fits into 700 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 6647.8
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.

Let's proceed to step 8:
78 goes into 760 9 times with a remainder of 58.
The next digit of our result is 9. 
Result so far: 6647.89
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
When dividing 580 by 78, we get 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 6647.897
Subtracting 546 from 580 leaves us 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.

On to step 10:
78 goes into 340 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 6647.8974
The remainder is 28 after subtracting 312 from 340.
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 11:
78 goes into 280 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 6647.89743
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
78 goes into 460 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 6647.897435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
78 goes into 700 8 times with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 6647.8974358
The remainder is 76 after subtracting 624 from 700.
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 14:
78 goes into 760 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 6647.89743589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 6647.89743589, with a leftover of 5.8e-08.
