4012755 divided by 863 
Let's see how many times 863 fits into 4012755.

Advancing to step 1:
4 divided by 863 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 863

Step 2:
863 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 863

Step 3:
863 can be fit into 401 0 times, resulting in a remainder of 401.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 401 leaves us with 401.
Bring next digit (2) of the dividend behind the 401 and repeat the process: 4012 / 863

Advancing to step 4:
When dividing 4012 by 863, we get 4 with a remainder of 560.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3452 from 4012 and we're left with 560.
Append the next digit (7) from the dividend to 560 and continue with: 5607 / 863

Moving on to step 5:
863 goes into 5607 6 times with a remainder of 429.
The next digit of our result is 6. 
Result so far: 46.0
Subtracting 5178 from 5607 leaves us with 429.
Append the next digit (5) from the dividend to 429 and continue with: 4295 / 863

Going ahead to step 6:
If we divide 4295 by 863, we get 4 and a remainder of 843.
The next digit of our result is 4. 
Result so far: 464.0
The remainder is 843 after subtracting 3452 from 4295.
Grab the next digit (5) from the dividend, add it to 843, then carry on: 8435 / 863

Going ahead to step 7:
When dividing 8435 by 863, we get 9 with a remainder of 668.
Write down 9 as next digit of the result. 
Result so far: 4649.0
If we take 7767 away from 8435, we end up with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Let's proceed to step 8:
6680 divided by 863 is 7 with a remainder of 639.
Record the quotient 7 as the next digit in the result. 
Result so far: 4649.7
If we take 6041 away from 6680, we end up with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Advancing to step 9:
The number 863 fits into 6390 7 times, leaving a remainder of 349.
Put 7 as the next digit of the answer. 
Result so far: 4649.77
Subtracting 6041 from 6390 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

The quotient of the division is 4649.77, and the remainder is 0.349.
