We're dividing 91173277 by 2 
We want to figure out the number of times 91173277 can be divided by 2.

Let's proceed to step 1:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 8 from 9 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Step 2:
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: 45.0
If we take 10 away from 11, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Step 3:
2 goes into 11 5 times with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 455.0
If we take 10 away from 11, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

On to step 4:
If we divide 17 by 2, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 4558.0
If we take 16 away from 17, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

Moving on to step 5:
If we divide 13 by 2, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 45586.0
If we subtract 12 from 13, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Step 6:
12 divided by 2 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 455866.0
Subtract 12 from 12 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Let's proceed to step 7:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 4558663.0
If we subtract 6 from 7, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Step 8:
2 can be fit into 17 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 45586638.0
Deduct 16 from 17 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 9:
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: 45586638.5
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.

Advancing to step 10:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45586638.5
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.

Going ahead to step 11:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 45586638.5
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.

In conclusion, the division gives 45586638.5 with a balance of 0.0.
