28365133 divided by 511 
The aim is to understand the frequency of 511 in 28365133.

Step 1:
If we divide 2 by 511, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 511

Step 2:
511 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 511

Moving on to step 3:
When dividing 283 by 511, we get 0 with a remainder of 283.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 283, we end up with 283.
Include the next digit (6) from the dividend after 283, then repeat: 2836 / 511

Moving on to step 4:
When dividing 2836 by 511, we get 5 with a remainder of 281.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 2555 away from 2836, we end up with 281.
Append the next digit (5) from the dividend to 281 and continue with: 2815 / 511

On to step 5:
The number 511 fits into 2815 5 times, leaving a remainder of 260.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtracting 2555 from 2815 leaves us with 260.
Grab the next digit (1) from the dividend, add it to 260, then carry on: 2601 / 511

On to step 6:
511 can be fit into 2601 5 times, resulting in a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 555.0
If we take 2555 away from 2601, we end up with 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 511

Let's proceed to step 7:
When dividing 463 by 511, we get 0 with a remainder of 463.
Put 0 as the next digit of the answer. 
Result so far: 5550.0
Subtract 0 from 463 to get 463.
Take the next digit (3) from the dividend and append it to 463, then repeat: 4633 / 511

Advancing to step 8:
When dividing 4633 by 511, we get 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 55509.0
If we take 4599 away from 4633, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
511 can be fit into 340 0 times, resulting in a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 55509.0
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 10:
511 can be fit into 3400 6 times, resulting in a remainder of 334.
The number 6 becomes the next digit in our result. 
Result so far: 55509.06
Subtract 3066 from 3400 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 11:
3340 divided by 511 is 6 with a remainder of 274.
Use 6 as the next digit of our solution. 
Result so far: 55509.066
If we subtract 3066 from 3340, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Our division results in 55509.066 with a remaining 0.0274.
