We look at the division of 82231272 by 15 
The aim is to understand the frequency of 15 in 82231272.

Let's proceed to step 1:
When dividing 8 by 15, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 15

Let's proceed to step 2:
The number 15 fits into 82 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 7 after subtracting 75 from 82.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 15

Advancing to step 3:
15 goes into 72 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtract 60 from 72 to get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 15

Advancing to step 4:
When dividing 123 by 15, we get 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 548.0
The remainder is 3 after subtracting 120 from 123.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 15

Advancing to step 5:
If we divide 31 by 15, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 5482.0
If we subtract 30 from 31, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 15

Going ahead to step 6:
The number 15 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 54820.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 15

Advancing to step 7:
If we divide 127 by 15, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 548208.0
If we take 120 away from 127, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 15

Moving on to step 8:
If we divide 72 by 15, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 5482084.0
If we subtract 60 from 72, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
The number 15 fits into 120 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 5482084.8
If we take 120 away from 120, we end up 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.

Let's proceed to step 10:
If we divide 0 by 15, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5482084.8
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.

Going ahead to step 11:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 5482084.8
If we subtract 0 from 0, we 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.

The final result is 5482084.8 with a remainder of 0.0.
