Let's divide 12304 by 77
The aim is to understand the frequency of 77 in 12304.

Step 1:
1 divided by 77 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 77

Moving on to step 2:
12 divided by 77 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 77

Advancing to step 3:
123 divided by 77 is 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 77 from 123, we get 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 77

Going ahead to step 4:
The number 77 fits into 460 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 385 from 460 leaves us with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 77

Step 5:
754 divided by 77 is 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
If we take 693 away from 754, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 6:
The number 77 fits into 610 7 times, leaving a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 159.7
Deduct 539 from 610 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 7:
77 can be fit into 710 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 159.79
Subtracting 693 from 710 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
170 divided by 77 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 159.792
Subtract 154 from 170 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 77, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 159.7922
Subtracting 154 from 160 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 159.7922, and the remainder is 6e-05.
