375431 divided by 76 
The aim is to understand the frequency of 76 in 375431.

Moving on to step 1:
3 divided by 76 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 76

Let's proceed to step 2:
76 goes into 37 0 times with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 76

Step 3:
The number 76 fits into 375 4 times, leaving a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 304 from 375 leaves us with 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 76

Let's proceed to step 4:
The number 76 fits into 714 9 times, leaving a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Deduct 684 from 714 and we're left with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 76

On to step 5:
76 goes into 303 3 times with a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 493.0
If we take 228 away from 303, we end up with 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 76

Advancing to step 6:
If we divide 751 by 76, we get 9 and a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 4939.0
Deduct 684 from 751 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 7:
670 divided by 76 is 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 4939.8
If we take 608 away from 670, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
76 can be fit into 620 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 4939.88
Deduct 608 from 620 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 4939.88 with a remaining 0.012.
