Let's divide 25348765 by 512
The aim is to understand the frequency of 512 in 25348765.

Advancing to step 1:
The number 512 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 512

Let's proceed to step 2:
If we divide 25 by 512, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 512

On to step 3:
512 goes into 253 0 times with a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 253 after subtracting 0 from 253.
Bring next digit (4) of the dividend behind the 253 and repeat the process: 2534 / 512

Let's proceed to step 4:
When dividing 2534 by 512, we get 4 with a remainder of 486.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2048 from 2534 to get 486.
Bring next digit (8) of the dividend behind the 486 and repeat the process: 4868 / 512

Let's proceed to step 5:
When dividing 4868 by 512, we get 9 with a remainder of 260.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Deduct 4608 from 4868 and we're left with 260.
Take the next digit (7) from the dividend and append it to 260, then repeat: 2607 / 512

Moving on to step 6:
If we divide 2607 by 512, we get 5 and a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 495.0
Subtract 2560 from 2607 to get 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 512

On to step 7:
512 can be fit into 476 0 times, resulting in a remainder of 476.
The next digit of our result is 0. 
Result so far: 4950.0
Subtract 0 from 476 to get 476.
Fetch the next digit (5) from the dividend, attach it to 476 and continue: 4765 / 512

Step 8:
4765 divided by 512 is 9 with a remainder of 157.
Use 9 as the next digit of our solution. 
Result so far: 49509.0
Deduct 4608 from 4765 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
512 can be fit into 1570 3 times, resulting in a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 49509.3
Subtract 1536 from 1570 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
If we divide 340 by 512, we get 0 and a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 49509.3
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 11:
If we divide 3400 by 512, we get 6 and a remainder of 328.
Write down 6 as next digit of the result. 
Result so far: 49509.306
Subtracting 3072 from 3400 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 12:
The number 512 fits into 3280 6 times, leaving a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 49509.3066
Subtracting 3072 from 3280 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final result is 49509.3066 with a remainder of 0.00208.
