We're dividing 503625 by 2 
We want to divide 503625 by 2.

On to step 1:
5 divided by 2 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 4 from 5 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Step 2:
If we divide 10 by 2, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 10 from 10 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Advancing to step 3:
If we divide 3 by 2, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 251.0
Subtract 2 from 3 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Going ahead to step 4:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 2518.0
If we subtract 16 from 16, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

On to step 5:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 25181.0
The remainder is 0 after subtracting 2 from 2.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Let's proceed to step 6:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 251812.0
The remainder is 1 after subtracting 4 from 5.
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:
If we divide 10 by 2, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 251812.5
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.

Step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 251812.5
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.

Going ahead to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 251812.5
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 quotient of the division is 251812.5, and the remainder is 0.0.
