We're dividing 561481 by 2 
We want to figure out the number of times 561481 can be divided by 2.

Step 1:
The number 2 fits into 5 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 4 from 5 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Going ahead to step 2:
2 can be fit into 16 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 0 after subtracting 16 from 16.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Going ahead to step 3:
2 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

Advancing to step 4:
The number 2 fits into 14 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 2807.0
Deduct 14 from 14 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 2

Advancing to step 5:
If we divide 8 by 2, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 28074.0
Subtract 8 from 8 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Advancing to step 6:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 280740.0
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.

Let's proceed to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 280740.5
Subtract 10 from 10 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.

Moving on to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 280740.5
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.

Moving on to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 280740.5
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.

The final outcome is 280740.5, with a leftover of 0.0.
