We look at the division of 636342 by 2 
We're looking to find how many times 2 goes into 636342.

Let's proceed to step 1:
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: 3.0
The remainder is 0 after subtracting 6 from 6.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

On to step 2:
3 divided by 2 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 2 from 3 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Going ahead to step 3:
16 divided by 2 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 318.0
Deduct 16 from 16 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Step 4:
If we divide 3 by 2, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 3181.0
If we take 2 away from 3, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Advancing to step 5:
If we divide 14 by 2, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 31817.0
Deduct 14 from 14 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

On to step 6:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 318171.0
Subtract 2 from 2 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.

Going ahead to step 7:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 318171.0
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.

Step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 318171.0
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.

The final result is 318171.0 with a remainder of 0.0.
