We look at the division of 83103080 by 2 
We're looking to find how many times 2 goes into 83103080.

On to step 1:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

Let's proceed to step 2:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtracting 2 from 3 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

On to step 3:
11 divided by 2 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 415.0
If we subtract 10 from 11, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Step 4:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 4155.0
Subtract 10 from 10 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

On to step 5:
When dividing 3 by 2, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 41551.0
Subtracting 2 from 3 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Advancing to step 6:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 415515.0
Subtracting 10 from 10 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

On to step 7:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4155154.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41551540.0
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.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41551540.0
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.

Step 10:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41551540.0
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.

The final outcome is 41551540.0, with a leftover of 0.0.
