We look at the division of 768559 by 78 
We want to divide 768559 by 78.

Step 1:
78 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 78

Advancing to step 2:
If we divide 76 by 78, we get 0 and a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Bring next digit (8) of the dividend behind the 76 and repeat the process: 768 / 78

On to step 3:
78 goes into 768 9 times with a remainder of 66.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 702 from 768, we get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 78

Moving on to step 4:
78 can be fit into 665 8 times, resulting in a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
The remainder is 41 after subtracting 624 from 665.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 78

Let's proceed to step 5:
If we divide 415 by 78, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 985.0
If we take 390 away from 415, we end up with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 78

Moving on to step 6:
If we divide 259 by 78, we get 3 and a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 9853.0
The remainder is 25 after subtracting 234 from 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
If we divide 250 by 78, we get 3 and a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 9853.3
Deduct 234 from 250 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
78 can be fit into 160 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 9853.32
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9853.32
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 9853.3205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
100 divided by 78 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 9853.32051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
78 goes into 220 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 9853.320512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
If we divide 640 by 78, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 9853.3205128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
If we divide 160 by 78, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 9853.32051282
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 9853.32051282 with a remainder of 4e-09.
