We're dividing 81514397 by 302 
The aim is to understand the frequency of 302 in 81514397.

Step 1:
When dividing 8 by 302, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 302

On to step 2:
When dividing 81 by 302, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 302

Step 3:
The number 302 fits into 815 2 times, leaving a remainder of 211.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 604 from 815 and we're left with 211.
Append the next digit (1) from the dividend to 211 and continue with: 2111 / 302

Moving on to step 4:
302 can be fit into 2111 6 times, resulting in a remainder of 299.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 1812 away from 2111, we end up with 299.
Append the next digit (4) from the dividend to 299 and continue with: 2994 / 302

Let's proceed to step 5:
If we divide 2994 by 302, we get 9 and a remainder of 276.
Write down 9 as next digit of the result. 
Result so far: 269.0
Subtract 2718 from 2994 to get 276.
Append the next digit (3) from the dividend to 276 and continue with: 2763 / 302

Going ahead to step 6:
2763 divided by 302 is 9 with a remainder of 45.
The next digit of our result is 9. 
Result so far: 2699.0
Subtract 2718 from 2763 to get 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 302

Moving on to step 7:
302 goes into 459 1 times with a remainder of 157.
The number 1 becomes the next digit in our result. 
Result so far: 26991.0
Subtract 302 from 459 to get 157.
Include the next digit (7) from the dividend after 157, then repeat: 1577 / 302

Going ahead to step 8:
302 can be fit into 1577 5 times, resulting in a remainder of 67.
Put 5 as the next digit of the answer. 
Result so far: 269915.0
If we take 1510 away from 1577, we end up 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 9:
670 divided by 302 is 2 with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 269915.2
If we take 604 away from 670, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
If we divide 660 by 302, we get 2 and a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 269915.22
Subtracting 604 from 660 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 269915.22, and the remainder is 0.056.
