We're dividing 332945 by 15 
The aim is to understand the frequency of 15 in 332945.

Let's proceed to step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 15

Moving on to step 2:
15 can be fit into 33 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 30 from 33 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 15

Step 3:
When dividing 32 by 15, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 30 from 32 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 15

On to step 4:
15 goes into 29 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 221.0
Subtracting 15 from 29 leaves us with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 15

Step 5:
15 goes into 144 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 2219.0
The remainder is 9 after subtracting 135 from 144.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 15

Advancing to step 6:
The number 15 fits into 95 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 22196.0
Subtracting 90 from 95 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 22196.3
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 22196.33
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 22196.33 and a remainder of 0.005.
