We look at the division of 40715631 by 315 
The aim is to understand the frequency of 315 in 40715631.

Let's proceed to step 1:
315 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 315

Step 2:
When dividing 40 by 315, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 315

On to step 3:
When dividing 407 by 315, we get 1 with a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 315 away from 407, we end up with 92.
Append the next digit (1) from the dividend to 92 and continue with: 921 / 315

Let's proceed to step 4:
921 divided by 315 is 2 with a remainder of 291.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 630 away from 921, we end up with 291.
Include the next digit (5) from the dividend after 291, then repeat: 2915 / 315

Going ahead to step 5:
315 can be fit into 2915 9 times, resulting in a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 129.0
If we take 2835 away from 2915, we end up with 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 315

Let's proceed to step 6:
When dividing 806 by 315, we get 2 with a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 1292.0
Subtract 630 from 806 to get 176.
Include the next digit (3) from the dividend after 176, then repeat: 1763 / 315

Going ahead to step 7:
The number 315 fits into 1763 5 times, leaving a remainder of 188.
Record the quotient 5 as the next digit in the result. 
Result so far: 12925.0
If we take 1575 away from 1763, we end up with 188.
Append the next digit (1) from the dividend to 188 and continue with: 1881 / 315

Step 8:
315 goes into 1881 5 times with a remainder of 306.
Use 5 as the next digit of our solution. 
Result so far: 129255.0
The remainder is 306 after subtracting 1575 from 1881.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 9:
315 can be fit into 3060 9 times, resulting in a remainder of 225.
Use 9 as the next digit of our solution. 
Result so far: 129255.9
Subtracting 2835 from 3060 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 10:
When dividing 2250 by 315, we get 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 129255.97
Subtracting 2205 from 2250 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
When dividing 450 by 315, we get 1 with a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 129255.971
Subtract 315 from 450 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 12:
The number 315 fits into 1350 4 times, leaving a remainder of 90.
The next digit of our result is 4. 
Result so far: 129255.9714
Subtract 1260 from 1350 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 13:
If we divide 900 by 315, we get 2 and a remainder of 270.
Write down 2 as next digit of the result. 
Result so far: 129255.97142
Subtract 630 from 900 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 14:
315 goes into 2700 8 times with a remainder of 180.
The next digit of our result is 8. 
Result so far: 129255.971428
Subtracting 2520 from 2700 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 15:
315 goes into 1800 5 times with a remainder of 225.
The next digit of our result is 5. 
Result so far: 129255.9714285
Subtracting 1575 from 1800 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 16:
The number 315 fits into 2250 7 times, leaving a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 129255.97142857
If we subtract 2205 from 2250, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 129255.97142857 and a remainder of 4.5e-08.
