Let's divide 43878854 by 256
We're looking to find how many times 256 goes into 43878854.

Step 1:
256 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 256

Let's proceed to step 2:
256 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 256

Going ahead to step 3:
438 divided by 256 is 1 with a remainder of 182.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 256 from 438 to get 182.
Take the next digit (7) from the dividend and append it to 182, then repeat: 1827 / 256

Advancing to step 4:
256 goes into 1827 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 1792 from 1827, we get 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 256

On to step 5:
256 goes into 358 1 times with a remainder of 102.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Subtracting 256 from 358 leaves us with 102.
Include the next digit (8) from the dividend after 102, then repeat: 1028 / 256

Step 6:
256 goes into 1028 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 1714.0
Subtracting 1024 from 1028 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 256

Going ahead to step 7:
256 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 17140.0
Subtract 0 from 45 to get 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 256

Advancing to step 8:
The number 256 fits into 454 1 times, leaving a remainder of 198.
Put 1 as the next digit of the answer. 
Result so far: 171401.0
If we take 256 away from 454, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 9:
256 can be fit into 1980 7 times, resulting in a remainder of 188.
Put 7 as the next digit of the answer. 
Result so far: 171401.7
If we take 1792 away from 1980, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 10:
If we divide 1880 by 256, we get 7 and a remainder of 88.
The number 7 becomes the next digit in our result. 
Result so far: 171401.77
The remainder is 88 after subtracting 1792 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 171401.77 with a remainder of 0.088.
