We look at the division of 279422 by 15 
The aim is to understand the frequency of 15 in 279422.

Advancing to step 1:
The number 15 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 15

Moving on to step 2:
When dividing 27 by 15, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 15 from 27 leaves us with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 15

Moving on to step 3:
15 can be fit into 129 8 times, resulting in a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 120 from 129, we get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 15

Advancing to step 4:
When dividing 94 by 15, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 186.0
Subtract 90 from 94 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 15

Going ahead to step 5:
When dividing 42 by 15, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 1862.0
Subtract 30 from 42 to get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 15

Let's proceed to step 6:
15 goes into 122 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 18628.0
Subtract 120 from 122 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
15 goes into 20 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 18628.1
Deduct 15 from 20 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.

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: 18628.13
If we subtract 45 from 50, we 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.

Moving on to step 9:
15 goes into 50 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 18628.133
Subtracting 45 from 50 leaves us 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.

In conclusion, the division gives 18628.133 with a balance of 0.0005.
