805246 ÷ 15 
The aim is to understand the frequency of 15 in 805246.

Advancing to step 1:
15 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our 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

Step 2:
80 divided by 15 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 75 from 80 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 15

Moving on to step 3:
55 divided by 15 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtract 45 from 55 to get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 15

Step 4:
15 goes into 102 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 536.0
The remainder is 12 after subtracting 90 from 102.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 15

Step 5:
15 can be fit into 124 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 5368.0
Deduct 120 from 124 and we're left with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 15

Step 6:
15 can be fit into 46 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 53683.0
If we subtract 45 from 46, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 15, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 53683.0
If we take 0 away from 10, 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.

Let's proceed to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 53683.06
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 15 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 53683.066
If we take 90 away from 100, 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.

The quotient of the division is 53683.066, and the remainder is 0.001.
