We divide 42503783 by 878
Let's see how many times 878 fits into 42503783.

Moving on to step 1:
If we divide 4 by 878, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 878

Step 2:
878 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 878

Advancing to step 3:
878 goes into 425 0 times with a remainder of 425.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 425 leaves us with 425.
Fetch the next digit (0) from the dividend, attach it to 425 and continue: 4250 / 878

Let's proceed to step 4:
The number 878 fits into 4250 4 times, leaving a remainder of 738.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3512 away from 4250, we end up with 738.
Take the next digit (3) from the dividend and append it to 738, then repeat: 7383 / 878

Going ahead to step 5:
If we divide 7383 by 878, we get 8 and a remainder of 359.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 7024 from 7383 leaves us with 359.
Take the next digit (7) from the dividend and append it to 359, then repeat: 3597 / 878

Advancing to step 6:
878 goes into 3597 4 times with a remainder of 85.
Use 4 as the next digit of our solution. 
Result so far: 484.0
Subtract 3512 from 3597 to get 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 878

Going ahead to step 7:
878 goes into 858 0 times with a remainder of 858.
Use 0 as the next digit of our solution. 
Result so far: 4840.0
If we subtract 0 from 858, we get 858.
Append the next digit (3) from the dividend to 858 and continue with: 8583 / 878

Moving on to step 8:
8583 divided by 878 is 9 with a remainder of 681.
Use 9 as the next digit of our solution. 
Result so far: 48409.0
The remainder is 681 after subtracting 7902 from 8583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Step 9:
6810 divided by 878 is 7 with a remainder of 664.
Put 7 as the next digit of the answer. 
Result so far: 48409.7
If we subtract 6146 from 6810, we get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 10:
878 can be fit into 6640 7 times, resulting in a remainder of 494.
Write down 7 as next digit of the result. 
Result so far: 48409.77
Subtracting 6146 from 6640 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

After the division, we end up with 48409.77 and a remainder of 0.494.
