639787 divided by 6 
Let's see how many times 6 fits into 639787.

Going ahead to step 1:
6 goes into 6 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 6

Let's proceed to step 2:
6 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
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

Advancing to step 3:
If we divide 39 by 6, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 106.0
The remainder is 3 after subtracting 36 from 39.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 6

Step 4:
When dividing 37 by 6, we get 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 1066.0
Subtract 36 from 37 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 6

Moving on to step 5:
When dividing 18 by 6, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 10663.0
If we subtract 18 from 18, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 6

Step 6:
The number 6 fits into 7 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 106631.0
Subtracting 6 from 7 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 6 fits into 10 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 106631.1
Deduct 6 from 10 and we're left 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.

On to step 8:
6 can be fit into 40 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 106631.16
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 9:
6 can be fit into 40 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 106631.166
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.

In conclusion, the division gives 106631.166 with a balance of 0.0004.
