We divide 415831 by 2
We want to figure out the number of times 415831 can be divided by 2.

Moving on to step 1:
If we divide 4 by 2, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Advancing to step 2:
2 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Step 3:
When dividing 15 by 2, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
Subtracting 14 from 15 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Advancing to step 4:
When dividing 18 by 2, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 2079.0
If we take 18 away from 18, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Going ahead to step 5:
When dividing 3 by 2, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 20791.0
If we subtract 2 from 3, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Advancing to step 6:
11 divided by 2 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 207915.0
The remainder is 1 after subtracting 10 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 207915.5
Deduct 10 from 10 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.

On to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 207915.5
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.

Moving on to step 9:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 207915.5
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 outcome is 207915.5, with a leftover of 0.0.
