We look at the division of 718665 by 15 
The aim is to understand the frequency of 15 in 718665.

Moving on to step 1:
15 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 15

Going ahead to step 2:
If we divide 71 by 15, we get 4 and a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 60 from 71, we get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 15

Moving on to step 3:
15 goes into 118 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 105 from 118 leaves us with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 15

On to step 4:
If we divide 136 by 15, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 479.0
Subtract 135 from 136 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 15

Moving on to step 5:
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: 4791.0
Subtract 15 from 16 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 15

Step 6:
15 divided by 15 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 47911.0
If we subtract 15 from 15, 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.

On to step 7:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 47911.0
The remainder is 0 after subtracting 0 from 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:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 47911.0
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 47911.0 with a remainder of 0.0.
