328719 divided by 15 
The aim is to understand the frequency of 15 in 328719.

Moving on to step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 15

Step 2:
When dividing 32 by 15, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 30 from 32 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 15

Let's proceed to step 3:
When dividing 28 by 15, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 15 from 28, we get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 15

On to step 4:
15 goes into 137 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 219.0
If we subtract 135 from 137, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 15

Advancing to step 5:
15 can be fit into 21 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 2191.0
Subtract 15 from 21 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 15

Step 6:
15 goes into 69 4 times with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 21914.0
If we take 60 away from 69, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 15 fits into 90 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 21914.6
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 15 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21914.6
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.

Let's proceed to step 9:
0 divided by 15 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21914.6
If we take 0 away from 0, we end up 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 quotient of the division is 21914.6, and the remainder is 0.0.
