We look at the division of 16531886 by 500 
The aim is to understand the frequency of 500 in 16531886.

Moving on to step 1:
If we divide 1 by 500, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 500

Let's proceed to step 2:
The number 500 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 500

Going ahead to step 3:
If we divide 165 by 500, we get 0 and a remainder of 165.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 165, we get 165.
Take the next digit (3) from the dividend and append it to 165, then repeat: 1653 / 500

On to step 4:
The number 500 fits into 1653 3 times, leaving a remainder of 153.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1500 from 1653 leaves us with 153.
Bring next digit (1) of the dividend behind the 153 and repeat the process: 1531 / 500

Going ahead to step 5:
500 goes into 1531 3 times with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 31 after subtracting 1500 from 1531.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 500

Step 6:
500 goes into 318 0 times with a remainder of 318.
Write down 0 as next digit of the result. 
Result so far: 330.0
Deduct 0 from 318 and we're left with 318.
Grab the next digit (8) from the dividend, add it to 318, then carry on: 3188 / 500

On to step 7:
When dividing 3188 by 500, we get 6 with a remainder of 188.
Record the quotient 6 as the next digit in the result. 
Result so far: 3306.0
Subtracting 3000 from 3188 leaves us with 188.
Append the next digit (6) from the dividend to 188 and continue with: 1886 / 500

On to step 8:
500 can be fit into 1886 3 times, resulting in a remainder of 386.
Put 3 as the next digit of the answer. 
Result so far: 33063.0
If we take 1500 away from 1886, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 9:
When dividing 3860 by 500, we get 7 with a remainder of 360.
Use 7 as the next digit of our solution. 
Result so far: 33063.7
The remainder is 360 after subtracting 3500 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 10:
If we divide 3600 by 500, we get 7 and a remainder of 100.
The next digit of our result is 7. 
Result so far: 33063.77
Subtracting 3500 from 3600 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 33063.77, with a leftover of 0.1.
