Let's divide 154243 by 2
We want to divide 154243 by 2.

Advancing to step 1:
2 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

On to step 2:
15 divided by 2 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 14 away from 15, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Advancing to step 3:
The number 2 fits into 14 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 77.0
If we take 14 away from 14, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Let's proceed to step 4:
2 divided by 2 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 771.0
Subtracting 2 from 2 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Advancing to step 5:
If we divide 4 by 2, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 7712.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Advancing to step 6:
The number 2 fits into 3 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 77121.0
The remainder is 1 after subtracting 2 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 2 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 77121.5
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.

Moving on to step 8:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 77121.5
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.

Let's proceed to step 9:
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: 77121.5
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.

In conclusion, the division gives 77121.5 with a balance of 0.0.
