587527 divided by 15 
The aim is to understand the frequency of 15 in 587527.

Moving on to step 1:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 15

Moving on to step 2:
58 divided by 15 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 13 after subtracting 45 from 58.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 15

Going ahead to step 3:
137 divided by 15 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 135 from 137 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 15

Let's proceed to step 4:
When dividing 25 by 15, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 391.0
Deduct 15 from 25 and we're left with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 15

On to step 5:
The number 15 fits into 102 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3916.0
Subtract 90 from 102 to get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 15

Step 6:
15 can be fit into 127 8 times, resulting in a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 39168.0
Subtract 120 from 127 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 15, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 39168.4
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 15 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 39168.46
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 39168.466
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 39168.466 and a remainder of 0.001.
