We look at the division of 30991676 by 715 
The aim is to understand the frequency of 715 in 30991676.

Step 1:
715 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 715

On to step 2:
715 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 715

Advancing to step 3:
The number 715 fits into 309 0 times, leaving a remainder of 309.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 309, we get 309.
Fetch the next digit (9) from the dividend, attach it to 309 and continue: 3099 / 715

On to step 4:
3099 divided by 715 is 4 with a remainder of 239.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2860 from 3099, we get 239.
Fetch the next digit (1) from the dividend, attach it to 239 and continue: 2391 / 715

Going ahead to step 5:
2391 divided by 715 is 3 with a remainder of 246.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 246 after subtracting 2145 from 2391.
Fetch the next digit (6) from the dividend, attach it to 246 and continue: 2466 / 715

Let's proceed to step 6:
715 can be fit into 2466 3 times, resulting in a remainder of 321.
The next digit of our result is 3. 
Result so far: 433.0
Subtract 2145 from 2466 to get 321.
Bring next digit (7) of the dividend behind the 321 and repeat the process: 3217 / 715

Moving on to step 7:
715 can be fit into 3217 4 times, resulting in a remainder of 357.
Record the quotient 4 as the next digit in the result. 
Result so far: 4334.0
Subtracting 2860 from 3217 leaves us with 357.
Take the next digit (6) from the dividend and append it to 357, then repeat: 3576 / 715

Moving on to step 8:
715 goes into 3576 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 43345.0
Subtracting 3575 from 3576 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
715 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 43345.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
100 divided by 715 is 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 43345.0
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 43345.0 with a remainder of 0.1.
