340890 ÷ 2 
Our goal is to divide 340890 by 2.

Going ahead to step 1:
3 divided by 2 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 2 from 3 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Moving on to step 2:
When dividing 14 by 2, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 14 from 14 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Let's proceed to step 3:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 170.0
If we subtract 0 from 0, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

Let's proceed to step 4:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 1704.0
Subtract 8 from 8 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Moving on to step 5:
9 divided by 2 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 17044.0
Subtract 8 from 9 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Step 6:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 170445.0
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.

Moving on to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 170445.0
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.

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 170445.0
If we subtract 0 from 0, we 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 quotient of the division is 170445.0, and the remainder is 0.0.
