Let's divide 4078180 by 403
Let's see how many times 403 fits into 4078180.

Step 1:
403 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 403

Let's proceed to step 2:
403 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 403

Step 3:
403 can be fit into 407 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 403 away from 407, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 403

Advancing to step 4:
403 goes into 48 0 times with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 403

Step 5:
The number 403 fits into 481 1 times, leaving a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtracting 403 from 481 leaves us with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 403

Going ahead to step 6:
788 divided by 403 is 1 with a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 1011.0
If we subtract 403 from 788, we get 385.
Bring next digit (0) of the dividend behind the 385 and repeat the process: 3850 / 403

Step 7:
403 goes into 3850 9 times with a remainder of 223.
Put 9 as the next digit of the answer. 
Result so far: 10119.0
Subtracting 3627 from 3850 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 8:
The number 403 fits into 2230 5 times, leaving a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 10119.5
Subtract 2015 from 2230 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 9:
403 can be fit into 2150 5 times, resulting in a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 10119.55
Subtract 2015 from 2150 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final result is 10119.55 with a remainder of 0.135.
