We look at the division of 227822 by 15 
The aim is to understand the frequency of 15 in 227822.

Advancing to step 1:
2 divided by 15 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 15

Moving on to step 2:
The number 15 fits into 22 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 15 from 22 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 15

Advancing to step 3:
When dividing 77 by 15, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 75 from 77 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 15

Let's proceed to step 4:
The number 15 fits into 28 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Deduct 15 from 28 and we're left with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 15

Let's proceed to step 5:
When dividing 132 by 15, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1518.0
Deduct 120 from 132 and we're left with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 15

Moving on to step 6:
If we divide 122 by 15, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 15188.0
If we take 120 away from 122, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
15 can be fit into 20 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 15188.1
The remainder is 5 after subtracting 15 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 15188.13
If we take 45 away from 50, we end up 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.

Advancing to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 15188.133
Deduct 45 from 50 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.

After the division, we end up with 15188.133 and a remainder of 0.0005.
