We look at the division of 868099 by 76 
The aim is to understand the frequency of 76 in 868099.

Going ahead to step 1:
If we divide 8 by 76, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 76

Moving on to step 2:
76 goes into 86 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 76 from 86, we get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 76

Moving on to step 3:
If we divide 108 by 76, we get 1 and a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 76 from 108 leaves us with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 76

On to step 4:
76 can be fit into 320 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
If we take 304 away from 320, we end up with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 76

Step 5:
When dividing 169 by 76, we get 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 1142.0
Deduct 152 from 169 and we're left with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 76

Moving on to step 6:
179 divided by 76 is 2 with a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 11422.0
Deduct 152 from 179 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
When dividing 270 by 76, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 11422.3
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
76 can be fit into 420 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 11422.35
Subtract 380 from 420 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
76 goes into 400 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 11422.355
Subtract 380 from 400 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.

The final result is 11422.355 with a remainder of 0.002.
