55521513 divided by 2 
Our goal is to divide 55521513 by 2.

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 take 4 away from 5, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Step 2:
When dividing 15 by 2, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 14 from 15 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 2

Going ahead to step 3:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 277.0
The remainder is 1 after subtracting 14 from 15.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Let's proceed to step 4:
When dividing 12 by 2, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 2776.0
Subtracting 12 from 12 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Advancing to step 5:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 27760.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

On to step 6:
15 divided by 2 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 277607.0
The remainder is 1 after subtracting 14 from 15.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Advancing to step 7:
When dividing 11 by 2, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 2776075.0
If we subtract 10 from 11, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 2

Moving on to step 8:
When dividing 13 by 2, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 27760756.0
If we subtract 12 from 13, we 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.

Moving on to step 9:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 27760756.5
If we subtract 10 from 10, 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 10:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 27760756.5
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.

Let's proceed to step 11:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27760756.5
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.

The final result is 27760756.5 with a remainder of 0.0.
