We look at the division of 51555003 by 2 
Our goal is to divide 51555003 by 2.

On to step 1:
When dividing 5 by 2, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 4 away from 5, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Let's proceed to step 2:
11 divided by 2 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 10 away from 11, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 2

Let's proceed to step 3:
15 divided by 2 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 257.0
Subtracting 14 from 15 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 2

Moving on to step 4:
15 divided by 2 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 2577.0
If we subtract 14 from 15, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

On to step 5:
If we divide 15 by 2, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 25777.0
The remainder is 1 after subtracting 14 from 15.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

On to step 6:
2 can be fit into 10 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 257775.0
If we subtract 10 from 10, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

On to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2577750.0
If we take 0 away from 0, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

On to step 8:
3 divided by 2 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 25777501.0
If we take 2 away from 3, 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.

Moving on to step 9:
When dividing 10 by 2, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 25777501.5
If we take 10 away from 10, 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.

On to step 10:
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: 25777501.5
If we subtract 0 from 0, we 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 11:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25777501.5
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.

The quotient of the division is 25777501.5, and the remainder is 0.0.
