12934541 divided by 512 
We want to figure out the number of times 12934541 can be divided by 512.

Going ahead to step 1:
1 divided by 512 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 512

On to step 2:
The number 512 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 512

Going ahead to step 3:
When dividing 129 by 512, we get 0 with a remainder of 129.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 129 after subtracting 0 from 129.
Append the next digit (3) from the dividend to 129 and continue with: 1293 / 512

On to step 4:
The number 512 fits into 1293 2 times, leaving a remainder of 269.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1024 from 1293 leaves us with 269.
Include the next digit (4) from the dividend after 269, then repeat: 2694 / 512

On to step 5:
When dividing 2694 by 512, we get 5 with a remainder of 134.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 134 after subtracting 2560 from 2694.
Append the next digit (5) from the dividend to 134 and continue with: 1345 / 512

Let's proceed to step 6:
When dividing 1345 by 512, we get 2 with a remainder of 321.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
If we subtract 1024 from 1345, we get 321.
Grab the next digit (4) from the dividend, add it to 321, then carry on: 3214 / 512

On to step 7:
The number 512 fits into 3214 6 times, leaving a remainder of 142.
The number 6 becomes the next digit in our result. 
Result so far: 2526.0
If we take 3072 away from 3214, we end up with 142.
Grab the next digit (1) from the dividend, add it to 142, then carry on: 1421 / 512

On to step 8:
512 goes into 1421 2 times with a remainder of 397.
Record the quotient 2 as the next digit in the result. 
Result so far: 25262.0
The remainder is 397 after subtracting 1024 from 1421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

On to step 9:
The number 512 fits into 3970 7 times, leaving a remainder of 386.
Use 7 as the next digit of our solution. 
Result so far: 25262.7
The remainder is 386 after subtracting 3584 from 3970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 10:
If we divide 3860 by 512, we get 7 and a remainder of 276.
Put 7 as the next digit of the answer. 
Result so far: 25262.77
Subtract 3584 from 3860 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The quotient of the division is 25262.77, and the remainder is 0.276.
