We're dividing 511248 by 15 
The aim is to understand the frequency of 15 in 511248.

Going ahead to step 1:
15 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 15

Let's proceed to step 2:
15 goes into 51 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 45 from 51, we get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 15

Moving on to step 3:
15 goes into 61 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we take 60 away from 61, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 15

Let's proceed to step 4:
If we divide 12 by 15, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 340.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 15

Moving on to step 5:
When dividing 124 by 15, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3408.0
Deduct 120 from 124 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 15

On to step 6:
15 goes into 48 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 34083.0
Subtracting 45 from 48 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
15 can be fit into 30 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 34083.2
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 34083.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34083.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 34083.2 with a balance of 0.0.
