We look at the division of 38534 by 15 
The aim is to understand the frequency of 15 in 38534.

Let's proceed to step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 15

Going ahead to step 2:
If we divide 38 by 15, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 8 after subtracting 30 from 38.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 15

On to step 3:
15 goes into 85 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 75 from 85 to get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 15

Moving on to step 4:
103 divided by 15 is 6 with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 256.0
Deduct 90 from 103 and we're left with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 15

Going ahead to step 5:
15 goes into 134 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 2568.0
Deduct 120 from 134 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 6:
The number 15 fits into 140 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 2568.9
Deduct 135 from 140 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.

Moving on to step 7:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 2568.93
Subtract 45 from 50 to 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.

Going ahead to step 8:
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: 2568.933
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.

After the division, we end up with 2568.933 and a remainder of 0.0005.
