Let's divide 80112658 by 2
Let's see how many times 2 fits into 80112658.

Let's proceed to step 1:
8 divided by 2 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Let's proceed to step 2:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

On to step 3:
2 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 400.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Let's proceed to step 4:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 4005.0
If we subtract 10 from 11, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Step 5:
If we divide 12 by 2, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 40056.0
The remainder is 0 after subtracting 12 from 12.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

On to step 6:
If we divide 6 by 2, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 400563.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Going ahead to step 7:
If we divide 5 by 2, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 4005632.0
Deduct 4 from 5 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Step 8:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 40056329.0
Subtract 18 from 18 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.

Let's proceed to step 9:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40056329.0
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.

Moving on to step 10:
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: 40056329.0
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.

The final result is 40056329.0 with a remainder of 0.0.
