203390 ÷ 2 
Let's see how many times 2 fits into 203390.

Step 1:
2 goes into 2 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 2 from 2 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

Moving on to step 2:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Moving on to step 3:
2 goes into 3 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we subtract 2 from 3, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 2

On to step 4:
If we divide 13 by 2, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 1016.0
Subtracting 12 from 13 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Let's proceed to step 5:
The number 2 fits into 19 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 10169.0
If we take 18 away from 19, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Going ahead to step 6:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 101695.0
Subtracting 10 from 10 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.

Moving on to step 7:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 101695.0
The remainder is 0 after subtracting 0 from 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:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 101695.0
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.

Our division results in 101695.0 with a remaining 0.0.
