We're dividing 770790 by 78 
We're looking to find how many times 78 goes into 770790.

Advancing to step 1:
7 divided by 78 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 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
Subtracting 0 from 77 leaves us with 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 78

Let's proceed to step 3:
770 divided by 78 is 9 with a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 68 after subtracting 702 from 770.
Fetch the next digit (7) from the dividend, attach it to 68 and continue: 687 / 78

Moving on to step 4:
78 goes into 687 8 times with a remainder of 63.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Deduct 624 from 687 and we're left with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 78

Going ahead to step 5:
78 goes into 639 8 times with a remainder of 15.
The next digit of our result is 8. 
Result so far: 988.0
Deduct 624 from 639 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 78

Let's proceed to step 6:
78 goes into 150 1 times with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 9881.0
The remainder is 72 after subtracting 78 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 7:
720 divided by 78 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 9881.9
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 9881.92
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 9881.923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
If we divide 60 by 78, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 9881.923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 78, we get 7 and a remainder of 54.
The next digit of our result is 7. 
Result so far: 9881.92307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 9881.923076
Subtract 468 from 540 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
720 divided by 78 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 9881.9230769
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
When dividing 180 by 78, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 9881.92307692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 9881.92307692 with a remaining 2.4e-08.
