We're dividing 143345 by 2 
Let's see how many times 2 fits into 143345.

Let's proceed to step 1:
2 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Step 2:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 14 from 14 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

On to step 3:
3 divided by 2 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Deduct 2 from 3 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Let's proceed to step 4:
2 can be fit into 13 6 times, resulting in a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 716.0
Subtract 12 from 13 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

On to step 5:
14 divided by 2 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7167.0
The remainder is 0 after subtracting 14 from 14.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Let's proceed to step 6:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 71672.0
Subtracting 4 from 5 leaves us 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:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 71672.5
Subtract 10 from 10 to 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.

Advancing 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: 71672.5
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.

Let's proceed to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 71672.5
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.

In conclusion, the division gives 71672.5 with a balance of 0.0.
