We're dividing 204781 by 15 
The aim is to understand the frequency of 15 in 204781.

Let's proceed to step 1:
15 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 15

Let's proceed to step 2:
15 goes into 20 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 15 from 20 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 15

Let's proceed to step 3:
15 can be fit into 54 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 45 from 54 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 15

Moving on to step 4:
The number 15 fits into 97 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 136.0
The remainder is 7 after subtracting 90 from 97.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 15

Advancing to step 5:
The number 15 fits into 78 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 1365.0
If we take 75 away from 78, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 15

Let's proceed to step 6:
The number 15 fits into 31 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 13652.0
Subtract 30 from 31 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
15 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 13652.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 13652.06
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 13652.066
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 13652.066, and the remainder is 0.001.
