We look at the division of 310487 by 76 
The aim is to understand the frequency of 76 in 310487.

Step 1:
When dividing 3 by 76, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 76

Let's proceed to step 2:
76 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 76

Going ahead to step 3:
76 can be fit into 310 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 304 from 310 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 76

Moving on to step 4:
64 divided by 76 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 64, we end up with 64.
Append the next digit (8) from the dividend to 64 and continue with: 648 / 76

Let's proceed to step 5:
76 can be fit into 648 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 408.0
Subtract 608 from 648 to get 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 76

On to step 6:
The number 76 fits into 407 5 times, leaving a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 4085.0
Subtract 380 from 407 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
76 goes into 270 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 4085.3
Subtract 228 from 270 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
76 goes into 420 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 4085.35
If we subtract 380 from 420, we 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:
The number 76 fits into 400 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 4085.355
Subtracting 380 from 400 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 4085.355 with a remaining 0.002.
