We're dividing 802158 by 15 
The aim is to understand the frequency of 15 in 802158.

On to step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 15

Advancing to step 2:
80 divided by 15 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 75 from 80 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 15

Moving on to step 3:
When dividing 52 by 15, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we subtract 45 from 52, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 15

Advancing to step 4:
15 can be fit into 71 4 times, resulting in a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 534.0
The remainder is 11 after subtracting 60 from 71.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 15

Advancing to step 5:
115 divided by 15 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 5347.0
Subtract 105 from 115 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 15

On to step 6:
When dividing 108 by 15, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 53477.0
Subtract 105 from 108 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 15 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 53477.2
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.

On to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 53477.2
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.

Let's proceed to step 9:
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: 53477.2
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 53477.2 with a balance of 0.0.
