Let's divide 18815318 by 512
The aim is to understand the frequency of 512 in 18815318.

Going ahead to step 1:
If we divide 1 by 512, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 512

On to step 2:
18 divided by 512 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 512

Advancing to step 3:
512 can be fit into 188 0 times, resulting in a remainder of 188.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 188 after subtracting 0 from 188.
Append the next digit (1) from the dividend to 188 and continue with: 1881 / 512

Step 4:
The number 512 fits into 1881 3 times, leaving a remainder of 345.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 1536 from 1881, we get 345.
Take the next digit (5) from the dividend and append it to 345, then repeat: 3455 / 512

Advancing to step 5:
512 can be fit into 3455 6 times, resulting in a remainder of 383.
The next digit of our result is 6. 
Result so far: 36.0
If we subtract 3072 from 3455, we get 383.
Take the next digit (3) from the dividend and append it to 383, then repeat: 3833 / 512

Let's proceed to step 6:
3833 divided by 512 is 7 with a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 367.0
Subtract 3584 from 3833 to get 249.
Include the next digit (1) from the dividend after 249, then repeat: 2491 / 512

On to step 7:
512 can be fit into 2491 4 times, resulting in a remainder of 443.
Write down 4 as next digit of the result. 
Result so far: 3674.0
Deduct 2048 from 2491 and we're left with 443.
Include the next digit (8) from the dividend after 443, then repeat: 4438 / 512

Going ahead to step 8:
If we divide 4438 by 512, we get 8 and a remainder of 342.
The next digit of our result is 8. 
Result so far: 36748.0
If we subtract 4096 from 4438, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 9:
512 goes into 3420 6 times with a remainder of 348.
Write down 6 as next digit of the result. 
Result so far: 36748.6
The remainder is 348 after subtracting 3072 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 10:
When dividing 3480 by 512, we get 6 with a remainder of 408.
Use 6 as the next digit of our solution. 
Result so far: 36748.66
If we subtract 3072 from 3480, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final result is 36748.66 with a remainder of 0.408.
