8393393 ÷ 315 
The aim is to understand the frequency of 315 in 8393393.

Advancing to step 1:
If we divide 8 by 315, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 315

On to step 2:
When dividing 83 by 315, we get 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 315

Moving on to step 3:
839 divided by 315 is 2 with a remainder of 209.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 630 away from 839, we end up with 209.
Take the next digit (3) from the dividend and append it to 209, then repeat: 2093 / 315

Advancing to step 4:
The number 315 fits into 2093 6 times, leaving a remainder of 203.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 1890 from 2093 and we're left with 203.
Take the next digit (3) from the dividend and append it to 203, then repeat: 2033 / 315

Moving on to step 5:
If we divide 2033 by 315, we get 6 and a remainder of 143.
The number 6 becomes the next digit in our result. 
Result so far: 266.0
The remainder is 143 after subtracting 1890 from 2033.
Include the next digit (9) from the dividend after 143, then repeat: 1439 / 315

Let's proceed to step 6:
1439 divided by 315 is 4 with a remainder of 179.
The number 4 becomes the next digit in our result. 
Result so far: 2664.0
If we take 1260 away from 1439, we end up with 179.
Take the next digit (3) from the dividend and append it to 179, then repeat: 1793 / 315

Going ahead to step 7:
1793 divided by 315 is 5 with a remainder of 218.
The number 5 becomes the next digit in our result. 
Result so far: 26645.0
If we take 1575 away from 1793, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 8:
315 goes into 2180 6 times with a remainder of 290.
Record the quotient 6 as the next digit in the result. 
Result so far: 26645.6
Subtracting 1890 from 2180 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 9:
2900 divided by 315 is 9 with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 26645.69
The remainder is 65 after subtracting 2835 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 10:
315 goes into 650 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 26645.692
The remainder is 20 after subtracting 630 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
315 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 26645.692
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
315 goes into 2000 6 times with a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 26645.69206
Deduct 1890 from 2000 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 13:
If we divide 1100 by 315, we get 3 and a remainder of 155.
Put 3 as the next digit of the answer. 
Result so far: 26645.692063
Subtracting 945 from 1100 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 14:
When dividing 1550 by 315, we get 4 with a remainder of 290.
Use 4 as the next digit of our solution. 
Result so far: 26645.6920634
If we subtract 1260 from 1550, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 15:
315 can be fit into 2900 9 times, resulting in a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 26645.69206349
Subtract 2835 from 2900 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 26645.69206349, with a leftover of 6.5e-08.
