We look at the division of 891433 by 2 
We want to figure out the number of times 891433 can be divided by 2.

Going ahead to step 1:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 8 from 8, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Moving on to step 2:
If we divide 9 by 2, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 8 away from 9, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Going ahead to step 3:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 445.0
The remainder is 1 after subtracting 10 from 11.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 2

Step 4:
14 divided by 2 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 4457.0
Deduct 14 from 14 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Advancing to step 5:
When dividing 3 by 2, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 44571.0
Subtracting 2 from 3 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 2

Going ahead to step 6:
2 can be fit into 13 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 445716.0
If we subtract 12 from 13, we get 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:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 445716.5
If we subtract 10 from 10, 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.

Moving on to step 8:
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: 445716.5
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.

Going ahead to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 445716.5
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.

Our division results in 445716.5 with a remaining 0.0.
