We're dividing 518855 by 77 
The aim is to understand the frequency of 77 in 518855.

On to step 1:
5 divided by 77 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 77

Step 2:
51 divided by 77 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 77

Advancing to step 3:
The number 77 fits into 518 6 times, leaving a remainder of 56.
The next digit of our result is 6. 
Result so far: 6.0
If we take 462 away from 518, we end up with 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 77

Going ahead to step 4:
568 divided by 77 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtracting 539 from 568 leaves us with 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 77

Let's proceed to step 5:
If we divide 295 by 77, we get 3 and a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 673.0
The remainder is 64 after subtracting 231 from 295.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 77

Let's proceed to step 6:
645 divided by 77 is 8 with a remainder of 29.
The next digit of our result is 8. 
Result so far: 6738.0
The remainder is 29 after subtracting 616 from 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 77 fits into 290 3 times, leaving a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 6738.3
The remainder is 59 after subtracting 231 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 8:
When dividing 590 by 77, we get 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 6738.37
The remainder is 51 after subtracting 539 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
77 can be fit into 510 6 times, resulting in a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 6738.376
If we subtract 462 from 510, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
The number 77 fits into 480 6 times, leaving a remainder of 18.
The next digit of our result is 6. 
Result so far: 6738.3766
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 6738.3766, and the remainder is 0.00018.
