Let's divide 530323 by 15
The aim is to understand the frequency of 15 in 530323.

Step 1:
15 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 15

On to step 2:
If we divide 53 by 15, we get 3 and a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 8 after subtracting 45 from 53.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 15

On to step 3:
15 can be fit into 80 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtracting 75 from 80 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 15

Moving on to step 4:
If we divide 53 by 15, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 353.0
Deduct 45 from 53 and we're left with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 15

On to step 5:
15 can be fit into 82 5 times, resulting in a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 3535.0
Deduct 75 from 82 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 15

Let's proceed to step 6:
If we divide 73 by 15, we get 4 and a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 35354.0
Deduct 60 from 73 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
130 divided by 15 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 35354.8
If we subtract 120 from 130, 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.

Advancing to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 35354.86
Subtracting 90 from 100 leaves us 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.

On to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 35354.866
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 quotient of the division is 35354.866, and the remainder is 0.001.
