We're dividing 639508 by 6 
We want to divide 639508 by 6.

Step 1:
When dividing 6 by 6, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 6 from 6 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 6

Let's proceed to step 2:
When dividing 3 by 6, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

Step 3:
If we divide 39 by 6, we get 6 and a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Subtract 36 from 39 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 6

Going ahead to step 4:
The number 6 fits into 35 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1065.0
Deduct 30 from 35 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 6

Moving on to step 5:
6 goes into 50 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 10658.0
If we take 48 away from 50, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 6

Advancing to step 6:
The number 6 fits into 28 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 106584.0
Subtracting 24 from 28 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
6 goes into 40 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 106584.6
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
40 divided by 6 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 106584.66
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 106584.66 and a remainder of 0.004.
