We're dividing 765790 by 993 
We're looking to find how many times 993 goes into 765790.

Going ahead to step 1:
993 can be fit into 7 0 times, resulting in 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.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 993

On to step 2:
76 divided by 993 is 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 993

Advancing to step 3:
The number 993 fits into 765 0 times, leaving a remainder of 765.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 765, we end up with 765.
Include the next digit (7) from the dividend after 765, then repeat: 7657 / 993

Going ahead to step 4:
The number 993 fits into 7657 7 times, leaving a remainder of 706.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 706 after subtracting 6951 from 7657.
Bring next digit (9) of the dividend behind the 706 and repeat the process: 7069 / 993

Going ahead to step 5:
When dividing 7069 by 993, we get 7 with a remainder of 118.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 6951 from 7069 leaves us with 118.
Append the next digit (0) from the dividend to 118 and continue with: 1180 / 993

Step 6:
If we divide 1180 by 993, we get 1 and a remainder of 187.
Use 1 as the next digit of our solution. 
Result so far: 771.0
If we take 993 away from 1180, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 7:
993 goes into 1870 1 times with a remainder of 877.
Put 1 as the next digit of the answer. 
Result so far: 771.1
Subtract 993 from 1870 to get 877.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8770, and continue the process.

On to step 8:
8770 divided by 993 is 8 with a remainder of 826.
Record the quotient 8 as the next digit in the result. 
Result so far: 771.18
The remainder is 826 after subtracting 7944 from 8770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Going ahead to step 9:
If we divide 8260 by 993, we get 8 and a remainder of 316.
Put 8 as the next digit of the answer. 
Result so far: 771.188
If we take 7944 away from 8260, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

The final result is 771.188 with a remainder of 0.0316.
