We're dividing 936063 by 15 
The aim is to understand the frequency of 15 in 936063.

Let's proceed to step 1:
15 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 15

Going ahead to step 2:
The number 15 fits into 93 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 90 from 93 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 15

Step 3:
15 goes into 36 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 62.0
The remainder is 6 after subtracting 30 from 36.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 15

On to step 4:
15 goes into 60 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 624.0
If we take 60 away from 60, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 15

On to step 5:
6 divided by 15 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 6240.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 15

Moving on to step 6:
15 can be fit into 63 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 62404.0
Subtract 60 from 63 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 15 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 62404.2
Subtracting 30 from 30 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 15 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62404.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 62404.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 62404.2 with a remainder of 0.0.
