We look at the division of 902231 by 76 
The aim is to understand the frequency of 76 in 902231.

Let's proceed to step 1:
The number 76 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 76

Moving on to step 2:
76 goes into 90 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 76 away from 90, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 76

Going ahead to step 3:
76 goes into 142 1 times with a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 76 from 142 leaves us with 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 76

Advancing to step 4:
The number 76 fits into 662 8 times, leaving a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Deduct 608 from 662 and we're left with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 76

Let's proceed to step 5:
76 goes into 543 7 times with a remainder of 11.
The next digit of our result is 7. 
Result so far: 1187.0
Subtracting 532 from 543 leaves us with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 76

Step 6:
111 divided by 76 is 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 11871.0
Subtracting 76 from 111 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
The number 76 fits into 350 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 11871.4
Subtracting 304 from 350 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
76 goes into 460 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 11871.46
If we take 456 away from 460, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 76 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11871.46
If we subtract 0 from 40, 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.

Step 10:
When dividing 400 by 76, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 11871.4605
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.

Step 11:
If we divide 200 by 76, we get 2 and a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 11871.46052
If we subtract 152 from 200, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
480 divided by 76 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 11871.460526
If we take 456 away from 480, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
240 divided by 76 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 11871.4605263
Deduct 228 from 240 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.

Going ahead to step 14:
76 goes into 120 1 times with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 11871.46052631
The remainder is 44 after subtracting 76 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 11871.46052631, with a leftover of 4.4e-08.
