We're dividing 553203 by 2 
Our goal is to divide 553203 by 2.

Let's proceed to step 1:
If we divide 5 by 2, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 4 from 5, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 2

Moving on to step 2:
If we divide 15 by 2, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 27.0
If we take 14 away from 15, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Going ahead to step 3:
When dividing 13 by 2, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 276.0
The remainder is 1 after subtracting 12 from 13.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Let's proceed to step 4:
When dividing 12 by 2, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 2766.0
Deduct 12 from 12 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

On to step 5:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27660.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Let's proceed to step 6:
2 can be fit into 3 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 276601.0
Subtract 2 from 3 to 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:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 276601.5
Deduct 10 from 10 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.

On 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: 276601.5
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 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: 276601.5
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.

The final result is 276601.5 with a remainder of 0.0.
