550861 divided by 2 
Let's see how many times 2 fits into 550861.

Let's proceed to step 1:
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: 2.0
If we subtract 4 from 5, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Going ahead to step 2:
When dividing 15 by 2, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 14 from 15 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Step 3:
2 goes into 10 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 275.0
Deduct 10 from 10 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Step 4:
8 divided by 2 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 2754.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

On to step 5:
When dividing 6 by 2, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 27543.0
Subtract 6 from 6 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Going ahead to step 6:
1 divided by 2 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 275430.0
Subtracting 0 from 1 leaves us 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 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: 275430.5
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.

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 275430.5
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.

On to step 9:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 275430.5
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 quotient of the division is 275430.5, and the remainder is 0.0.
