409395 ÷ 28 
Our goal is to divide 409395 by 28.

Step 1:
When dividing 4 by 28, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 28

Moving on to step 2:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 12 after subtracting 28 from 40.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 28

Advancing to step 3:
28 can be fit into 129 4 times, resulting in a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 112 from 129, we get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 28

Going ahead to step 4:
The number 28 fits into 173 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Deduct 168 from 173 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 28

Let's proceed to step 5:
When dividing 59 by 28, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 1462.0
Deduct 56 from 59 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 28

Going ahead to step 6:
28 goes into 35 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 14621.0
If we take 28 away from 35, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
28 can be fit into 70 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 14621.2
If we take 56 away from 70, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
140 divided by 28 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 14621.25
Deduct 140 from 140 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
28 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14621.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
28 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14621.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 14621.25, with a leftover of 0.0.
