Let's divide 331549 by 2
We're looking to find how many times 2 goes into 331549.

Step 1:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 2 from 3.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Going ahead to step 2:
The number 2 fits into 13 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 12 from 13 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Advancing to step 3:
2 can be fit into 11 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
If we subtract 10 from 11, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Let's proceed to step 4:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1657.0
Subtracting 14 from 15 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

On to step 5:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 16577.0
Subtracting 14 from 14 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

On to step 6:
The number 2 fits into 9 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 165774.0
If we take 8 away from 9, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
2 goes into 10 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 165774.5
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 165774.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 165774.5
Subtract 0 from 0 to get 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 165774.5 with a remainder of 0.0.
