80200 divided by 15 
The aim is to understand the frequency of 15 in 80200.

Advancing to step 1:
15 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 15

Going ahead to 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
Subtracting 75 from 80 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 15

Advancing to step 3:
When dividing 52 by 15, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 53.0
If we subtract 45 from 52, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 15

Going ahead to step 4:
15 can be fit into 70 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 534.0
Deduct 60 from 70 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 15

Let's proceed to step 5:
If we divide 100 by 15, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 5346.0
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.

On to step 6:
100 divided by 15 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 5346.6
Subtract 90 from 100 to 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.

Advancing to step 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 5346.66
Subtracting 90 from 100 leaves us 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 final outcome is 5346.66, with a leftover of 0.01.
