We're dividing 40127350 by 904 
Let's see how many times 904 fits into 40127350.

Step 1:
If we divide 4 by 904, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 904

Step 2:
904 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 904

Advancing to step 3:
The number 904 fits into 401 0 times, leaving a remainder of 401.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 401 leaves us with 401.
Grab the next digit (2) from the dividend, add it to 401, then carry on: 4012 / 904

On to step 4:
4012 divided by 904 is 4 with a remainder of 396.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3616 from 4012 to get 396.
Take the next digit (7) from the dividend and append it to 396, then repeat: 3967 / 904

On to step 5:
If we divide 3967 by 904, we get 4 and a remainder of 351.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 3616 from 3967 to get 351.
Include the next digit (3) from the dividend after 351, then repeat: 3513 / 904

Step 6:
904 can be fit into 3513 3 times, resulting in a remainder of 801.
The number 3 becomes the next digit in our result. 
Result so far: 443.0
Deduct 2712 from 3513 and we're left with 801.
Include the next digit (5) from the dividend after 801, then repeat: 8015 / 904

Moving on to step 7:
904 can be fit into 8015 8 times, resulting in a remainder of 783.
Put 8 as the next digit of the answer. 
Result so far: 4438.0
Deduct 7232 from 8015 and we're left with 783.
Grab the next digit (0) from the dividend, add it to 783, then carry on: 7830 / 904

On to step 8:
7830 divided by 904 is 8 with a remainder of 598.
Use 8 as the next digit of our solution. 
Result so far: 44388.0
Subtracting 7232 from 7830 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Step 9:
When dividing 5980 by 904, we get 6 with a remainder of 556.
The number 6 becomes the next digit in our result. 
Result so far: 44388.6
Subtract 5424 from 5980 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 10:
When dividing 5560 by 904, we get 6 with a remainder of 136.
Write down 6 as next digit of the result. 
Result so far: 44388.66
If we subtract 5424 from 5560, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 44388.66 and a remainder of 0.136.
