520679 ÷ 78 
Let's see how many times 78 fits into 520679.

Step 1:
The number 78 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 78

Step 2:
78 can be fit into 52 0 times, resulting in a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 78

Let's proceed to step 3:
78 can be fit into 520 6 times, resulting in a remainder of 52.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 468 from 520, we get 52.
Grab the next digit (6) from the dividend, add it to 52, then carry on: 526 / 78

Let's proceed to step 4:
The number 78 fits into 526 6 times, leaving a remainder of 58.
The next digit of our result is 6. 
Result so far: 66.0
Deduct 468 from 526 and we're left with 58.
Bring next digit (7) of the dividend behind the 58 and repeat the process: 587 / 78

Moving on to step 5:
587 divided by 78 is 7 with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 667.0
If we subtract 546 from 587, we get 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 78

Step 6:
If we divide 419 by 78, we get 5 and a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 6675.0
Subtract 390 from 419 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 78 fits into 290 3 times, leaving a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 6675.3
If we subtract 234 from 290, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 8:
560 divided by 78 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 6675.37
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
When dividing 140 by 78, we get 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 6675.371
Subtracting 78 from 140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
620 divided by 78 is 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 6675.3717
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 6675.37179
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
If we divide 380 by 78, we get 4 and a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 6675.371794
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 13:
The number 78 fits into 680 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 6675.3717948
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
560 divided by 78 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 6675.37179487
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 6675.37179487 with a balance of 1.4e-08.
