We look at the division of 40329407 by 864 
Let's see how many times 864 fits into 40329407.

Advancing to step 1:
The number 864 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 864

Let's proceed to step 2:
When dividing 40 by 864, we get 0 with 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.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 864

Moving on to step 3:
864 can be fit into 403 0 times, resulting in a remainder of 403.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 403 leaves us with 403.
Bring next digit (2) of the dividend behind the 403 and repeat the process: 4032 / 864

Step 4:
The number 864 fits into 4032 4 times, leaving a remainder of 576.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 3456 from 4032 to get 576.
Take the next digit (9) from the dividend and append it to 576, then repeat: 5769 / 864

Going ahead to step 5:
5769 divided by 864 is 6 with a remainder of 585.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 5184 away from 5769, we end up with 585.
Fetch the next digit (4) from the dividend, attach it to 585 and continue: 5854 / 864

Let's proceed to step 6:
5854 divided by 864 is 6 with a remainder of 670.
Put 6 as the next digit of the answer. 
Result so far: 466.0
If we subtract 5184 from 5854, we get 670.
Bring next digit (0) of the dividend behind the 670 and repeat the process: 6700 / 864

Step 7:
If we divide 6700 by 864, we get 7 and a remainder of 652.
The number 7 becomes the next digit in our result. 
Result so far: 4667.0
Subtract 6048 from 6700 to get 652.
Take the next digit (7) from the dividend and append it to 652, then repeat: 6527 / 864

Step 8:
When dividing 6527 by 864, we get 7 with a remainder of 479.
Put 7 as the next digit of the answer. 
Result so far: 46677.0
Subtract 6048 from 6527 to get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Moving on to step 9:
864 can be fit into 4790 5 times, resulting in a remainder of 470.
The next digit of our result is 5. 
Result so far: 46677.5
Subtract 4320 from 4790 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 10:
864 goes into 4700 5 times with a remainder of 380.
The number 5 becomes the next digit in our result. 
Result so far: 46677.55
Subtract 4320 from 4700 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

After the division, we end up with 46677.55 and a remainder of 0.38.
