We look at the division of 150948 by 15 
The aim is to understand the frequency of 15 in 150948.

Let's proceed to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 15

Moving on to step 2:
15 can be fit into 15 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 15 from 15 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 15

On to step 3:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 15

On to step 4:
If we divide 9 by 15, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 15

Let's proceed to step 5:
The number 15 fits into 94 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1006.0
Deduct 90 from 94 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 15

Going ahead to step 6:
15 goes into 48 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 10063.0
If we subtract 45 from 48, we 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.

Going ahead to step 7:
When dividing 30 by 15, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 10063.2
Deduct 30 from 30 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.

Going ahead to step 8:
0 divided by 15 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10063.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10063.2
If we subtract 0 from 0, we get 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 10063.2 with a remainder of 0.0.
