We divide 415685 by 2
Let's see how many times 2 fits into 415685.

Moving on to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
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

Moving on to step 2:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Step 3:
15 divided by 2 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 207.0
The remainder is 1 after subtracting 14 from 15.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

On to step 4:
2 can be fit into 16 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 2078.0
Subtract 16 from 16 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

On to step 5:
2 goes into 8 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 20784.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

On to step 6:
5 divided by 2 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 207842.0
Subtract 4 from 5 to 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.

On to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 207842.5
If we take 10 away from 10, 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.

Advancing to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 207842.5
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 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 207842.5
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 quotient of the division is 207842.5, and the remainder is 0.0.
