111909 ÷ 2 
We're looking to find how many times 2 goes into 111909.

On to step 1:
If we divide 1 by 2, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

Moving on to step 2:
2 can be fit into 11 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 10 from 11 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

Step 3:
If we divide 11 by 2, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 55.0
If we take 10 away from 11, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Going ahead to step 4:
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: 559.0
Subtract 18 from 19 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Going ahead to step 5:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5595.0
If we subtract 10 from 10, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Going ahead to step 6:
When dividing 9 by 2, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 55954.0
Subtract 8 from 9 to 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.

Going ahead to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 55954.5
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.

Going ahead to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 55954.5
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.

Going ahead to step 9:
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: 55954.5
If we take 0 away from 0, 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.

In conclusion, the division gives 55954.5 with a balance of 0.0.
