223709 ÷ 2 
We want to figure out the number of times 223709 can be divided by 2.

Going ahead to step 1:
2 can be fit into 2 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 2 from 2.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

On to step 2:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 2 from 2 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Let's proceed to step 3:
The number 2 fits into 3 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 111.0
If we take 2 away from 3, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Going ahead to step 4:
When dividing 17 by 2, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 1118.0
The remainder is 1 after subtracting 16 from 17.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Let's proceed to step 5:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11185.0
If we subtract 10 from 10, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Step 6:
When dividing 9 by 2, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 111854.0
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.

Let's proceed to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 111854.5
If we subtract 10 from 10, 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.

On to step 8:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 111854.5
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.

On to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 111854.5
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.

After the division, we end up with 111854.5 and a remainder of 0.0.
