We're dividing 254145 by 2 
We're looking to find how many times 2 goes into 254145.

Going ahead to step 1:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 2 from 2 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

On to step 2:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 4 away from 5, 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:
2 goes into 14 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we subtract 14 from 14, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Going ahead to step 4:
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: 1270.0
Subtract 0 from 1 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

On to step 5:
If we divide 14 by 2, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 12707.0
If we subtract 14 from 14, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

On to step 6:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 127072.0
If we subtract 4 from 5, we 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.

Let's proceed to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 127072.5
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:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 127072.5
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.

Let's proceed to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 127072.5
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.

The quotient of the division is 127072.5, and the remainder is 0.0.
