We look at the division of 76708556 by 84 
The aim is to understand the frequency of 84 in 76708556.

Step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 84

Step 2:
The number 84 fits into 76 0 times, leaving a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (7) from the dividend after 76, then repeat: 767 / 84

Going ahead to step 3:
84 goes into 767 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 756 from 767 and we're left with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 84

Step 4:
110 divided by 84 is 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we subtract 84 from 110, we get 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 84

Moving on to step 5:
If we divide 268 by 84, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 913.0
If we subtract 252 from 268, we get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 84

Let's proceed to step 6:
If we divide 165 by 84, we get 1 and a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 9131.0
Deduct 84 from 165 and we're left with 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 84

Moving on to step 7:
When dividing 815 by 84, we get 9 with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 91319.0
Subtracting 756 from 815 leaves us with 59.
Fetch the next digit (6) from the dividend, attach it to 59 and continue: 596 / 84

Advancing to step 8:
596 divided by 84 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 913197.0
The remainder is 8 after subtracting 588 from 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 84 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 913197.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 84 is 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 913197.09
Subtracting 756 from 800 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
The number 84 fits into 440 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 913197.095
Subtract 420 from 440 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 913197.0952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
84 goes into 320 3 times with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 913197.09523
Subtracting 252 from 320 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
680 divided by 84 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 913197.095238
Subtract 672 from 680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 15:
If we divide 80 by 84, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 913197.095238
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
800 divided by 84 is 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 913197.09523809
If we subtract 756 from 800, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 913197.09523809 and a remainder of 4.4e-08.
