728186 divided by 2 
Let's see how many times 2 fits into 728186.

Step 1:
2 can be fit into 7 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 6 from 7, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Moving on to step 2:
2 goes into 12 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 12 from 12 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

Moving on to step 3:
When dividing 8 by 2, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 364.0
If we take 8 away from 8, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Advancing to step 4:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 3640.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Let's proceed to step 5:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 36409.0
If we take 18 away from 18, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Let's proceed to step 6:
6 divided by 2 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 364093.0
If we take 6 away from 6, we end up 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.

Moving on to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 364093.0
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.

Let's proceed to step 8:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 364093.0
Deduct 0 from 0 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.

The final result is 364093.0 with a remainder of 0.0.
