We look at the division of 45297385 by 512 
The aim is to understand the frequency of 512 in 45297385.

Moving on to step 1:
512 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 512

Let's proceed to step 2:
The number 512 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 512

Step 3:
If we divide 452 by 512, we get 0 and a remainder of 452.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 452 after subtracting 0 from 452.
Bring next digit (9) of the dividend behind the 452 and repeat the process: 4529 / 512

Step 4:
512 can be fit into 4529 8 times, resulting in a remainder of 433.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 4096 from 4529 and we're left with 433.
Include the next digit (7) from the dividend after 433, then repeat: 4337 / 512

Going ahead to step 5:
4337 divided by 512 is 8 with a remainder of 241.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtract 4096 from 4337 to get 241.
Include the next digit (3) from the dividend after 241, then repeat: 2413 / 512

On to step 6:
512 can be fit into 2413 4 times, resulting in a remainder of 365.
The next digit of our result is 4. 
Result so far: 884.0
If we take 2048 away from 2413, we end up with 365.
Bring next digit (8) of the dividend behind the 365 and repeat the process: 3658 / 512

Going ahead to step 7:
512 can be fit into 3658 7 times, resulting in a remainder of 74.
The next digit of our result is 7. 
Result so far: 8847.0
Subtract 3584 from 3658 to get 74.
Grab the next digit (5) from the dividend, add it to 74, then carry on: 745 / 512

On to step 8:
If we divide 745 by 512, we get 1 and a remainder of 233.
Record the quotient 1 as the next digit in the result. 
Result so far: 88471.0
The remainder is 233 after subtracting 512 from 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 9:
512 can be fit into 2330 4 times, resulting in a remainder of 282.
Write down 4 as next digit of the result. 
Result so far: 88471.4
Subtract 2048 from 2330 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 10:
The number 512 fits into 2820 5 times, leaving a remainder of 260.
The next digit of our result is 5. 
Result so far: 88471.45
Subtracting 2560 from 2820 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
The number 512 fits into 2600 5 times, leaving a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 88471.455
Subtracting 2560 from 2600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 88471.455 and a remainder of 0.004.
