We're dividing 53457751 by 512 
The aim is to understand the frequency of 512 in 53457751.

Advancing to step 1:
If we divide 5 by 512, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 512

Advancing to step 2:
512 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 512

Let's proceed to step 3:
512 goes into 534 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 512 from 534, we get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 512

Going ahead to step 4:
512 can be fit into 225 0 times, resulting in a remainder of 225.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 225 to get 225.
Grab the next digit (7) from the dividend, add it to 225, then carry on: 2257 / 512

Step 5:
The number 512 fits into 2257 4 times, leaving a remainder of 209.
Put 4 as the next digit of the answer. 
Result so far: 104.0
The remainder is 209 after subtracting 2048 from 2257.
Append the next digit (7) from the dividend to 209 and continue with: 2097 / 512

Step 6:
If we divide 2097 by 512, we get 4 and a remainder of 49.
The next digit of our result is 4. 
Result so far: 1044.0
If we take 2048 away from 2097, we end up with 49.
Include the next digit (5) from the dividend after 49, then repeat: 495 / 512

Step 7:
495 divided by 512 is 0 with a remainder of 495.
Write down 0 as next digit of the result. 
Result so far: 10440.0
Deduct 0 from 495 and we're left with 495.
Append the next digit (1) from the dividend to 495 and continue with: 4951 / 512

Going ahead to step 8:
When dividing 4951 by 512, we get 9 with a remainder of 343.
The number 9 becomes the next digit in our result. 
Result so far: 104409.0
The remainder is 343 after subtracting 4608 from 4951.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 9:
The number 512 fits into 3430 6 times, leaving a remainder of 358.
Put 6 as the next digit of the answer. 
Result so far: 104409.6
If we subtract 3072 from 3430, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 10:
If we divide 3580 by 512, we get 6 and a remainder of 508.
Record the quotient 6 as the next digit in the result. 
Result so far: 104409.66
Deduct 3072 from 3580 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Our division results in 104409.66 with a remaining 0.508.
