11521 ÷ 2 
Our goal is to divide 11521 by 2.

Advancing to step 1:
2 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Going ahead to step 2:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 10 away from 11, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Let's proceed to step 3:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtract 14 from 15 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

On to step 4:
12 divided by 2 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 576.0
If we subtract 12 from 12, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Step 5:
When dividing 1 by 2, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 5760.0
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 6:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 5760.5
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
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: 5760.5
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 8:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5760.5
If we take 0 away from 0, we end up 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 final result is 5760.5 with a remainder of 0.0.
