We're dividing 772663 by 78 
We want to figure out the number of times 772663 can be divided by 78.

Advancing to step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 78

Step 2:
The number 78 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 78

Moving on to step 3:
772 divided by 78 is 9 with a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 702 from 772 to get 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 78

On to step 4:
If we divide 706 by 78, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 99.0
Subtracting 702 from 706 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 78

On to step 5:
78 goes into 46 0 times with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 990.0
Subtracting 0 from 46 leaves us with 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 78

Let's proceed to step 6:
463 divided by 78 is 5 with a remainder of 73.
Record the quotient 5 as the next digit in the result. 
Result so far: 9905.0
The remainder is 73 after subtracting 390 from 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
The number 78 fits into 730 9 times, leaving a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9905.9
The remainder is 28 after subtracting 702 from 730.
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 8:
If we divide 280 by 78, we get 3 and a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 9905.93
Deduct 234 from 280 and we're left 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.

Step 9:
460 divided by 78 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 9905.935
If we subtract 390 from 460, we get 70.
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 10:
700 divided by 78 is 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 9905.9358
If we take 624 away from 700, we end up with 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 11:
When dividing 760 by 78, we get 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 9905.93589
If we subtract 702 from 760, we 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.

Going ahead to step 12:
78 goes into 580 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 9905.935897
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.

Going ahead to step 13:
If we divide 340 by 78, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 9905.9358974
Subtracting 312 from 340 leaves us 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.

Step 14:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 9905.93589743
Subtracting 234 from 280 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.

The final result is 9905.93589743 with a remainder of 4.6e-08.
