We look at the division of 41015028 by 399 
We're looking to find how many times 399 goes into 41015028.

On to step 1:
When dividing 4 by 399, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 399

Going ahead to step 2:
399 can be fit into 41 0 times, resulting in a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 399

Moving on to step 3:
399 goes into 410 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 399 away from 410, we end up with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 399

Going ahead to step 4:
If we divide 111 by 399, we get 0 and a remainder of 111.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 111 after subtracting 0 from 111.
Grab the next digit (5) from the dividend, add it to 111, then carry on: 1115 / 399

Moving on to step 5:
399 goes into 1115 2 times with a remainder of 317.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 798 away from 1115, we end up with 317.
Take the next digit (0) from the dividend and append it to 317, then repeat: 3170 / 399

Advancing to step 6:
When dividing 3170 by 399, we get 7 with a remainder of 377.
Put 7 as the next digit of the answer. 
Result so far: 1027.0
Subtracting 2793 from 3170 leaves us with 377.
Take the next digit (2) from the dividend and append it to 377, then repeat: 3772 / 399

Step 7:
399 can be fit into 3772 9 times, resulting in a remainder of 181.
The next digit of our result is 9. 
Result so far: 10279.0
Subtracting 3591 from 3772 leaves us with 181.
Take the next digit (8) from the dividend and append it to 181, then repeat: 1818 / 399

Advancing to step 8:
When dividing 1818 by 399, we get 4 with a remainder of 222.
Use 4 as the next digit of our solution. 
Result so far: 102794.0
If we subtract 1596 from 1818, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 9:
2220 divided by 399 is 5 with a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 102794.5
The remainder is 225 after subtracting 1995 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 10:
The number 399 fits into 2250 5 times, leaving a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 102794.55
If we subtract 1995 from 2250, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final outcome is 102794.55, with a leftover of 0.255.
