859649 divided by 2 
We want to figure out the number of times 859649 can be divided by 2.

Advancing to step 1:
8 divided by 2 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Moving on to step 2:
If we divide 5 by 2, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 42.0
If we take 4 away from 5, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Moving on to step 3:
When dividing 19 by 2, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 429.0
Subtract 18 from 19 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 2

Going ahead to step 4:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 4298.0
Subtracting 16 from 16 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

On to step 5:
4 divided by 2 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 42982.0
Subtract 4 from 4 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Going ahead to step 6:
When dividing 9 by 2, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 429824.0
The remainder is 1 after subtracting 8 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 429824.5
If we take 10 away from 10, we end up 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:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 429824.5
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.

Going ahead to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 429824.5
Subtracting 0 from 0 leaves us 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 429824.5, and the remainder is 0.0.
