840954 ÷ 2 
We want to figure out the number of times 840954 can be divided by 2.

On to step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 8 from 8 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

On to step 2:
If we divide 4 by 2, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 4 from 4 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

Moving on to step 3:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 420.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

On to step 4:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4204.0
Subtract 8 from 9 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Going ahead to step 5:
2 can be fit into 15 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 42047.0
The remainder is 1 after subtracting 14 from 15.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Let's proceed to step 6:
If we divide 14 by 2, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 420477.0
Subtract 14 from 14 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.

Going ahead to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 420477.0
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.

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: 420477.0
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.

After the division, we end up with 420477.0 and a remainder of 0.0.
