8573 ÷ 2 
Our goal is to divide 8573 by 2.

Advancing to step 1:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Let's proceed 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: 42.0
Subtract 4 from 5 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Step 3:
The number 2 fits into 17 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 428.0
Subtract 16 from 17 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Step 4:
When dividing 13 by 2, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 4286.0
Subtracting 12 from 13 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.

Moving on to step 5:
If we divide 10 by 2, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4286.5
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.

Going ahead to step 6:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4286.5
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.

Advancing to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4286.5
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 4286.5 with a balance of 0.0.
