We look at the division of 67241 by 15 
The aim is to understand the frequency of 15 in 67241.

Moving on to step 1:
6 divided by 15 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 15

Advancing to step 2:
67 divided by 15 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 7 after subtracting 60 from 67.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 15

Let's proceed to step 3:
If we divide 72 by 15, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 44.0
The remainder is 12 after subtracting 60 from 72.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 15

Advancing to step 4:
124 divided by 15 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 448.0
Subtract 120 from 124 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 15

Advancing to step 5:
15 goes into 41 2 times with a remainder of 11.
The next digit of our result is 2. 
Result so far: 4482.0
The remainder is 11 after subtracting 30 from 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 6:
110 divided by 15 is 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 4482.7
Subtracting 105 from 110 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.

On to step 7:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 4482.73
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.

Going ahead to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 4482.733
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.

The quotient of the division is 4482.733, and the remainder is 0.0005.
