45576672 ÷ 2 
We want to figure out the number of times 45576672 can be divided by 2.

Step 1:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Step 2:
When dividing 5 by 2, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 1 after subtracting 4 from 5.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

On to step 3:
2 goes into 15 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 227.0
If we subtract 14 from 15, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Going ahead to step 4:
2 can be fit into 17 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 2278.0
If we subtract 16 from 17, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

Advancing to step 5:
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: 22788.0
Subtracting 16 from 16 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Going ahead to step 6:
6 divided by 2 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 227883.0
If we take 6 away from 6, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 2

Advancing to step 7:
If we divide 7 by 2, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 2278833.0
Subtracting 6 from 7 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Going ahead to step 8:
2 goes into 12 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 22788336.0
If we subtract 12 from 12, 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.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22788336.0
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.

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: 22788336.0
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 final result is 22788336.0 with a remainder of 0.0.
