We divide 503551 by 2
We want to figure out the number of times 503551 can be divided by 2.

Moving on to step 1:
2 goes into 5 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 4 from 5, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Advancing to step 2:
10 divided by 2 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 0 after subtracting 10 from 10.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Let's proceed to step 3:
When dividing 3 by 2, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 251.0
If we subtract 2 from 3, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Step 4:
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: 2517.0
Subtract 14 from 15 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Step 5:
15 divided by 2 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 25177.0
If we subtract 14 from 15, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Going ahead to step 6:
When dividing 11 by 2, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 251775.0
If we take 10 away from 11, we end up 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.

Step 7:
2 goes into 10 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 251775.5
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.

Step 8:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 251775.5
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.
The number 0 becomes the next digit in our result. 
Result so far: 251775.5
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 251775.5 with a remainder of 0.0.
