770766 divided by 51 
We want to figure out the number of times 770766 can be divided by 51.

Step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 51

On to step 2:
77 divided by 51 is 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 51 from 77 leaves us with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 51

Moving on to step 3:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 255 from 260, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 51

On to step 4:
57 divided by 51 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 151.0
Subtract 51 from 57 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 51

Advancing to step 5:
When dividing 66 by 51, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1511.0
If we take 51 away from 66, we end up with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 51

Step 6:
If we divide 156 by 51, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 15113.0
The remainder is 3 after subtracting 153 from 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 51 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 15113.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 51 fits into 300 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 15113.05
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
When dividing 450 by 51, we get 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 15113.058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
51 goes into 420 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 15113.0588
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 15113.0588 with a remaining 0.00012.
