We look at the division of 775981 by 78 
We're looking to find how many times 78 goes into 775981.

Going ahead to step 1:
7 divided by 78 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 78

Step 2:
78 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 78

Going ahead to step 3:
If we divide 775 by 78, we get 9 and a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 702 from 775 leaves us with 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 78

On to step 4:
78 can be fit into 739 9 times, resulting in a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 702 from 739 leaves us with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 78

Advancing to step 5:
78 can be fit into 378 4 times, resulting in a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 994.0
If we take 312 away from 378, we end up with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 78

Step 6:
If we divide 661 by 78, we get 8 and a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 9948.0
Subtracting 624 from 661 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
When dividing 370 by 78, we get 4 with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 9948.4
If we take 312 away from 370, we end up 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.

Let's proceed to step 8:
If we divide 580 by 78, we get 7 and a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 9948.47
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.

Moving on to step 9:
78 can be fit into 340 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 9948.474
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 10:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 9948.4743
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.

Moving on to step 11:
78 goes into 460 5 times with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 9948.47435
Subtract 390 from 460 to 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.

Advancing to step 12:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 9948.474358
If we subtract 624 from 700, we 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.

Advancing to step 13:
When dividing 760 by 78, we get 9 with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 9948.4743589
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.

On to step 14:
When dividing 580 by 78, we get 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 9948.47435897
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.

The final outcome is 9948.47435897, with a leftover of 3.4e-08.
