We look at the division of 52140669 by 256 
Our goal is to divide 52140669 by 256.

Advancing to step 1:
When dividing 5 by 256, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 256

Going ahead to step 2:
If we divide 52 by 256, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 256

Let's proceed to step 3:
If we divide 521 by 256, we get 2 and a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 512 from 521 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 256

Moving on to step 4:
256 can be fit into 94 0 times, resulting in a remainder of 94.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 94 to get 94.
Take the next digit (0) from the dividend and append it to 94, then repeat: 940 / 256

Going ahead to step 5:
256 can be fit into 940 3 times, resulting in a remainder of 172.
Write down 3 as next digit of the result. 
Result so far: 203.0
Deduct 768 from 940 and we're left with 172.
Grab the next digit (6) from the dividend, add it to 172, then carry on: 1726 / 256

Step 6:
If we divide 1726 by 256, we get 6 and a remainder of 190.
The number 6 becomes the next digit in our result. 
Result so far: 2036.0
Subtracting 1536 from 1726 leaves us with 190.
Fetch the next digit (6) from the dividend, attach it to 190 and continue: 1906 / 256

Moving on to step 7:
256 goes into 1906 7 times with a remainder of 114.
Put 7 as the next digit of the answer. 
Result so far: 20367.0
If we subtract 1792 from 1906, we get 114.
Bring next digit (9) of the dividend behind the 114 and repeat the process: 1149 / 256

On to step 8:
If we divide 1149 by 256, we get 4 and a remainder of 125.
The number 4 becomes the next digit in our result. 
Result so far: 203674.0
Subtract 1024 from 1149 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
If we divide 1250 by 256, we get 4 and a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 203674.4
If we subtract 1024 from 1250, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 10:
256 goes into 2260 8 times with a remainder of 212.
Use 8 as the next digit of our solution. 
Result so far: 203674.48
If we subtract 2048 from 2260, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 11:
If we divide 2120 by 256, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 203674.488
Subtract 2048 from 2120 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 203674.488 with a remainder of 0.0072.
