We look at the division of 83005648 by 315 
The aim is to understand the frequency of 315 in 83005648.

Going ahead to step 1:
8 divided by 315 is 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.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 315

Step 2:
315 goes into 83 0 times with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Append the next digit (0) from the dividend to 83 and continue with: 830 / 315

Advancing to step 3:
315 goes into 830 2 times with a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 630 from 830 and we're left with 200.
Fetch the next digit (0) from the dividend, attach it to 200 and continue: 2000 / 315

Step 4:
When dividing 2000 by 315, we get 6 with a remainder of 110.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 1890 from 2000 and we're left with 110.
Append the next digit (5) from the dividend to 110 and continue with: 1105 / 315

Let's proceed to step 5:
315 can be fit into 1105 3 times, resulting in a remainder of 160.
The number 3 becomes the next digit in our result. 
Result so far: 263.0
Subtract 945 from 1105 to get 160.
Include the next digit (6) from the dividend after 160, then repeat: 1606 / 315

On to step 6:
If we divide 1606 by 315, we get 5 and a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 2635.0
Deduct 1575 from 1606 and we're left with 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 315

Moving on to step 7:
If we divide 314 by 315, we get 0 and a remainder of 314.
Record the quotient 0 as the next digit in the result. 
Result so far: 26350.0
Deduct 0 from 314 and we're left with 314.
Take the next digit (8) from the dividend and append it to 314, then repeat: 3148 / 315

On to step 8:
3148 divided by 315 is 9 with a remainder of 313.
Record the quotient 9 as the next digit in the result. 
Result so far: 263509.0
The remainder is 313 after subtracting 2835 from 3148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 9:
If we divide 3130 by 315, we get 9 and a remainder of 295.
The next digit of our result is 9. 
Result so far: 263509.9
Deduct 2835 from 3130 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 10:
When dividing 2950 by 315, we get 9 with a remainder of 115.
The number 9 becomes the next digit in our result. 
Result so far: 263509.99
The remainder is 115 after subtracting 2835 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Our division results in 263509.99 with a remaining 0.115.
