We look at the division of 316332 by 15 
The aim is to understand the frequency of 15 in 316332.

Let's proceed to step 1:
15 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 15

Advancing to step 2:
The number 15 fits into 31 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 30 from 31 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 15

Let's proceed to step 3:
When dividing 16 by 15, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 15 away from 16, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 15

Going ahead to step 4:
15 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
Subtract 0 from 13 to get 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 15

Advancing to step 5:
If we divide 133 by 15, we get 8 and a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 2108.0
If we take 120 away from 133, we end up with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 15

Step 6:
When dividing 132 by 15, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 21088.0
Subtracting 120 from 132 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
If we divide 120 by 15, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 21088.8
Subtracting 120 from 120 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.

Step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21088.8
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.

Advancing to step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21088.8
Subtract 0 from 0 to 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 21088.8 with a remainder of 0.0.
