We're dividing 657367 by 15 
The aim is to understand the frequency of 15 in 657367.

Let's proceed to step 1:
15 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 15

Let's proceed to step 2:
65 divided by 15 is 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 60 away from 65, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 15

On to step 3:
15 goes into 57 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtract 45 from 57 to get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 15

Step 4:
The number 15 fits into 123 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 438.0
If we subtract 120 from 123, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 15

Advancing to step 5:
When dividing 36 by 15, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 4382.0
Subtracting 30 from 36 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 15

Step 6:
The number 15 fits into 67 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 43824.0
If we subtract 60 from 67, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
15 goes into 70 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 43824.4
Subtract 60 from 70 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.

Advancing to step 8:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 43824.46
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.

Step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 43824.466
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.

Our division results in 43824.466 with a remaining 0.001.
