We divide 27891 by 2
We want to figure out the number of times 27891 can be divided by 2.

On to step 1:
2 divided by 2 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 2 from 2.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 2

Step 2:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 6 from 7 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Step 3:
18 divided by 2 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtract 18 from 18 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Advancing to step 4:
If we divide 9 by 2, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 1394.0
Subtracting 8 from 9 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

Let's proceed to step 5:
When dividing 11 by 2, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 13945.0
Deduct 10 from 11 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 6:
If we divide 10 by 2, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 13945.5
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 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13945.5
If we take 0 away from 0, 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.

Let's proceed to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13945.5
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.

In conclusion, the division gives 13945.5 with a balance of 0.0.
