We look at the division of 638601 by 3 
We want to figure out the number of times 638601 can be divided by 3.

Going ahead to step 1:
6 divided by 3 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 0 after subtracting 6 from 6.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Advancing to step 2:
3 goes into 3 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 0 after subtracting 3 from 3.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

On to step 3:
The number 3 fits into 8 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 212.0
If we subtract 6 from 8, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Advancing to step 4:
If we divide 26 by 3, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 2128.0
Subtracting 24 from 26 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Step 5:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 21286.0
If we subtract 18 from 20, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 3

Let's proceed to step 6:
When dividing 21 by 3, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 212867.0
Subtract 21 from 21 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.

Moving on 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: 212867.0
Subtract 0 from 0 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.

Moving on to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 212867.0
Subtract 0 from 0 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.

In conclusion, the division gives 212867.0 with a balance of 0.0.
