We're dividing 805001 by 15 
The aim is to understand the frequency of 15 in 805001.

Going ahead to step 1:
15 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 15

Let's proceed to step 2:
80 divided by 15 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 75 from 80 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 15

Advancing to step 3:
15 can be fit into 55 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we subtract 45 from 55, we get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 15

Moving on to step 4:
15 goes into 100 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 536.0
If we subtract 90 from 100, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 15

Going ahead to step 5:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 5366.0
Subtract 90 from 100 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 15

Advancing to step 6:
When dividing 101 by 15, we get 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 53666.0
Subtracting 90 from 101 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
15 goes into 110 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 53666.7
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 53666.73
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.

Going ahead to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 53666.733
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 53666.733, with a leftover of 0.0005.
