We divide 80415 by 2
We want to divide 80415 by 2.

On to step 1:
2 goes into 8 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Let's proceed to step 2:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Moving on to step 3:
2 can be fit into 4 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 402.0
Subtract 4 from 4 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Advancing to step 4:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 4020.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 2

Advancing to step 5:
When dividing 15 by 2, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 40207.0
If we subtract 14 from 15, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
2 goes into 10 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 40207.5
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.

Let's proceed to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40207.5
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 8:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40207.5
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.

The final result is 40207.5 with a remainder of 0.0.
