315364 ÷ 30 
The aim is to understand the frequency of 30 in 315364.

On to step 1:
3 divided by 30 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 30

On to step 2:
The number 30 fits into 31 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 30 from 31 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 30

Going ahead to step 3:
30 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 15 to get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 30

Going ahead to step 4:
153 divided by 30 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
If we take 150 away from 153, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 30

Advancing to step 5:
When dividing 36 by 30, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1051.0
Subtracting 30 from 36 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 30

Step 6:
30 can be fit into 64 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 10512.0
Subtract 60 from 64 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
When dividing 40 by 30, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 10512.1
If we take 30 away from 40, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
30 goes into 100 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 10512.13
Subtract 90 from 100 to 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 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 10512.133
If we subtract 90 from 100, 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.

The final result is 10512.133 with a remainder of 0.001.
