Let's divide 30717291 by 302
The aim is to understand the frequency of 302 in 30717291.

Let's proceed to step 1:
The number 302 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 302

Step 2:
302 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 302

On to step 3:
307 divided by 302 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 5 after subtracting 302 from 307.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 302

Step 4:
If we divide 51 by 302, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 302

Moving on to step 5:
If we divide 517 by 302, we get 1 and a remainder of 215.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we take 302 away from 517, we end up with 215.
Include the next digit (2) from the dividend after 215, then repeat: 2152 / 302

Advancing to step 6:
When dividing 2152 by 302, we get 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 1017.0
Subtracting 2114 from 2152 leaves us with 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 302

On to step 7:
302 can be fit into 389 1 times, resulting in a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 10171.0
Subtract 302 from 389 to get 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 302

On to step 8:
871 divided by 302 is 2 with a remainder of 267.
Use 2 as the next digit of our solution. 
Result so far: 101712.0
Subtract 604 from 871 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 9:
When dividing 2670 by 302, we get 8 with a remainder of 254.
The number 8 becomes the next digit in our result. 
Result so far: 101712.8
If we subtract 2416 from 2670, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 10:
2540 divided by 302 is 8 with a remainder of 124.
The number 8 becomes the next digit in our result. 
Result so far: 101712.88
Subtract 2416 from 2540 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final outcome is 101712.88, with a leftover of 0.124.
