Let's divide 529363 by 15
The aim is to understand the frequency of 15 in 529363.

Going ahead to step 1:
When dividing 5 by 15, we get 0 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.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 15

Let's proceed to step 2:
If we divide 52 by 15, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 45 from 52, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 15

Advancing to step 3:
When dividing 79 by 15, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 75 from 79 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 15

Going ahead to step 4:
43 divided by 15 is 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 352.0
If we subtract 30 from 43, we get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 15

Moving on to step 5:
The number 15 fits into 136 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 3529.0
The remainder is 1 after subtracting 135 from 136.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 15

Step 6:
15 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 35290.0
If we take 0 away from 13, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 15, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 35290.8
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 35290.86
Deduct 90 from 100 and we're left 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:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 35290.866
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 35290.866 with a balance of 0.001.
