We're dividing 58408618 by 256 
Our goal is to divide 58408618 by 256.

Step 1:
5 divided by 256 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 256

Let's proceed to step 2:
If we divide 58 by 256, we get 0 and a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 256

Going ahead to step 3:
584 divided by 256 is 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 512 from 584 leaves us with 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 256

Advancing to step 4:
256 can be fit into 720 2 times, resulting in a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 512 from 720, we get 208.
Append the next digit (8) from the dividend to 208 and continue with: 2088 / 256

Advancing to step 5:
The number 256 fits into 2088 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 228.0
If we subtract 2048 from 2088, we get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 256

Advancing to step 6:
If we divide 406 by 256, we get 1 and a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 2281.0
Deduct 256 from 406 and we're left with 150.
Include the next digit (1) from the dividend after 150, then repeat: 1501 / 256

Let's proceed to step 7:
256 goes into 1501 5 times with a remainder of 221.
Use 5 as the next digit of our solution. 
Result so far: 22815.0
If we take 1280 away from 1501, we end up with 221.
Bring next digit (8) of the dividend behind the 221 and repeat the process: 2218 / 256

Let's proceed to step 8:
256 goes into 2218 8 times with a remainder of 170.
The next digit of our result is 8. 
Result so far: 228158.0
Subtracting 2048 from 2218 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 9:
256 can be fit into 1700 6 times, resulting in a remainder of 164.
Write down 6 as next digit of the result. 
Result so far: 228158.6
If we subtract 1536 from 1700, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 10:
1640 divided by 256 is 6 with a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 228158.66
The remainder is 104 after subtracting 1536 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 228158.66 with a remainder of 0.104.
