Let's divide 335921 by 2
We're looking to find how many times 2 goes into 335921.

Going ahead to step 1:
2 goes into 3 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 2 away from 3, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

Going ahead to step 2:
13 divided by 2 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 12 away from 13, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Advancing to step 3:
2 can be fit into 15 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
Subtract 14 from 15 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Step 4:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1679.0
If we take 18 away from 19, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Let's proceed to step 5:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 16796.0
If we take 12 away from 12, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Step 6:
If we divide 1 by 2, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 167960.0
If we subtract 0 from 1, we get 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:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 167960.5
If we take 10 away from 10, 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.

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: 167960.5
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.

Step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 167960.5
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 result is 167960.5 with a remainder of 0.0.
