We look at the division of 636888 by 3 
Let's see how many times 3 fits into 636888.

Going ahead to step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 6 from 6 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Going ahead to step 2:
When dividing 3 by 3, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

Let's proceed to step 3:
The number 3 fits into 6 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 212.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

On to step 4:
The number 3 fits into 8 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2122.0
If we take 6 away from 8, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

Let's proceed to step 5:
28 divided by 3 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 21229.0
If we subtract 27 from 28, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Moving on to step 6:
3 can be fit into 18 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 212296.0
The remainder is 0 after subtracting 18 from 18.
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:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 212296.0
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:
3 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 212296.0
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 212296.0 with a remainder of 0.0.
