288121 divided by 2 
Our goal is to divide 288121 by 2.

Moving on to step 1:
2 divided by 2 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 2 from 2 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Going ahead to step 2:
2 goes into 8 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 8 from 8, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Moving on to step 3:
8 divided by 2 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

On to step 4:
If we divide 1 by 2, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 1440.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Advancing to step 5:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 14406.0
Subtract 12 from 12 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Let's proceed to step 6:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 144060.0
Subtracting 0 from 1 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.

On 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: 144060.5
Subtracting 10 from 10 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.

Advancing to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 144060.5
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.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 144060.5
Subtract 0 from 0 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.

After the division, we end up with 144060.5 and a remainder of 0.0.
