Let's divide 385430 by 15
The aim is to understand the frequency of 15 in 385430.

On 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
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 15

Let's proceed to step 2:
If we divide 38 by 15, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 30 from 38 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 15

Advancing to step 3:
The number 15 fits into 85 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 75 from 85 leaves us with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 15

Going ahead to step 4:
15 can be fit into 104 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 256.0
Subtract 90 from 104 to get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 15

Moving on to step 5:
143 divided by 15 is 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 2569.0
The remainder is 8 after subtracting 135 from 143.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 15

Moving on to step 6:
The number 15 fits into 80 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 25695.0
Subtracting 75 from 80 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.

Going ahead to step 7:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 25695.3
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.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 25695.33
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.

In conclusion, the division gives 25695.33 with a balance of 0.005.
