243760 ÷ 2 
We're looking to find how many times 2 goes into 243760.

Step 1:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 2 from 2, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Let's proceed to step 2:
2 goes into 4 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Going ahead to step 3:
2 can be fit into 3 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
The remainder is 1 after subtracting 2 from 3.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 2

On to step 4:
The number 2 fits into 17 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 1218.0
Deduct 16 from 17 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

Going ahead to step 5:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 12188.0
If we take 16 away from 16, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Step 6:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 121880.0
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.

Step 7:
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: 121880.0
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:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 121880.0
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.

Our division results in 121880.0 with a remaining 0.0.
