8128 divided by 77 
The aim is to understand the frequency of 77 in 8128.

Let's proceed to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 77

Step 2:
77 can be fit into 81 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 77 away from 81, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 77

Going ahead to step 3:
If we divide 42 by 77, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 77

Going ahead to step 4:
77 can be fit into 428 5 times, resulting in a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
If we take 385 away from 428, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 5:
430 divided by 77 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 105.5
If we subtract 385 from 430, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 6:
450 divided by 77 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 105.55
Deduct 385 from 450 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 105.55 with a remainder of 0.065.
