20206509 divided by 499 
The aim is to understand the frequency of 499 in 20206509.

Step 1:
The number 499 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 499

Moving on to step 2:
The number 499 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 499

Advancing to step 3:
When dividing 202 by 499, we get 0 with a remainder of 202.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 202 to get 202.
Include the next digit (0) from the dividend after 202, then repeat: 2020 / 499

Step 4:
If we divide 2020 by 499, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 1996 from 2020, we get 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 499

On to step 5:
499 goes into 246 0 times with a remainder of 246.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 246 leaves us with 246.
Take the next digit (5) from the dividend and append it to 246, then repeat: 2465 / 499

Moving on to step 6:
499 can be fit into 2465 4 times, resulting in a remainder of 469.
Write down 4 as next digit of the result. 
Result so far: 404.0
Subtract 1996 from 2465 to get 469.
Append the next digit (0) from the dividend to 469 and continue with: 4690 / 499

Advancing to step 7:
The number 499 fits into 4690 9 times, leaving a remainder of 199.
The next digit of our result is 9. 
Result so far: 4049.0
If we subtract 4491 from 4690, we get 199.
Bring next digit (9) of the dividend behind the 199 and repeat the process: 1999 / 499

Step 8:
1999 divided by 499 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 40494.0
If we subtract 1996 from 1999, we get 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 9:
499 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 40494.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 499 fits into 300 0 times, leaving a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 40494.0
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 40494.0, with a leftover of 0.3.
