We're dividing 551981 by 2 
We want to divide 551981 by 2.

On to step 1:
2 goes into 5 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 4 from 5 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Going ahead to step 2:
The number 2 fits into 15 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 14 from 15, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Going ahead to step 3:
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: 275.0
Deduct 10 from 11 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Moving on to step 4:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2759.0
Subtract 18 from 19 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Going ahead to step 5:
When dividing 18 by 2, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 27599.0
Subtracting 18 from 18 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Going ahead to step 6:
1 divided by 2 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 275990.0
Deduct 0 from 1 and we're left 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.

Advancing to step 7:
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: 275990.5
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.

Let's proceed 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: 275990.5
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.

On to step 9:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 275990.5
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 275990.5, and the remainder is 0.0.
