We divide 71880 by 15
The aim is to understand the frequency of 15 in 71880.

Moving on to step 1:
7 divided by 15 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 15

Let's proceed to step 2:
The number 15 fits into 71 4 times, leaving a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 60 from 71 leaves us with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 15

Step 3:
15 can be fit into 118 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 105 from 118, we get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 15

Going ahead to step 4:
The number 15 fits into 138 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 479.0
The remainder is 3 after subtracting 135 from 138.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 15

On to step 5:
15 can be fit into 30 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 4792.0
The remainder is 0 after subtracting 30 from 30.
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 6:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4792.0
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.

Moving on to step 7:
When dividing 0 by 15, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4792.0
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.

The quotient of the division is 4792.0, and the remainder is 0.0.
