779287 ÷ 78 
Let's see how many times 78 fits into 779287.

Moving on to step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 78

Let's proceed to step 2:
78 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 78

Moving on to step 3:
The number 78 fits into 779 9 times, leaving a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 77 after subtracting 702 from 779.
Grab the next digit (2) from the dividend, add it to 77, then carry on: 772 / 78

Advancing to step 4:
When dividing 772 by 78, we get 9 with a remainder of 70.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 70 after subtracting 702 from 772.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 78

Advancing to step 5:
708 divided by 78 is 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 999.0
The remainder is 6 after subtracting 702 from 708.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 78

Going ahead to step 6:
If we divide 67 by 78, we get 0 and a remainder of 67.
The next digit of our result is 0. 
Result so far: 9990.0
If we subtract 0 from 67, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
670 divided by 78 is 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 9990.8
Subtracting 624 from 670 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 9990.85
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
700 divided by 78 is 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 9990.858
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.

Step 10:
78 goes into 760 9 times with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 9990.8589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 9990.85897
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
78 can be fit into 340 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 9990.858974
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
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: 9990.8589743
If we subtract 234 from 280, we 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.

Let's proceed to step 14:
460 divided by 78 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 9990.85897435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 9990.85897435 with a remaining 7e-08.
