We're dividing 638367 by 3 
We want to figure out the number of times 638367 can be divided by 3.

On to step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 6 away from 6, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

On to step 2:
3 goes into 3 1 times 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.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

On to step 3:
3 goes into 8 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 212.0
The remainder is 2 after subtracting 6 from 8.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Step 4:
If we divide 23 by 3, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 2127.0
The remainder is 2 after subtracting 21 from 23.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Let's proceed to step 5:
If we divide 26 by 3, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 21278.0
The remainder is 2 after subtracting 24 from 26.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Advancing to step 6:
3 can be fit into 27 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 212789.0
If we take 27 away from 27, 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.

Going ahead to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 212789.0
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.

Step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 212789.0
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.

After the division, we end up with 212789.0 and a remainder of 0.0.
