639254 divided by 6 
We want to figure out the number of times 639254 can be divided by 6.

Let's proceed to step 1:
6 divided by 6 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 6

Moving on to step 2:
6 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 6

Step 3:
39 divided by 6 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Deduct 36 from 39 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 6

Going ahead to step 4:
32 divided by 6 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 1065.0
Deduct 30 from 32 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 6

Moving on to step 5:
6 goes into 25 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 10654.0
The remainder is 1 after subtracting 24 from 25.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 6

Let's proceed to step 6:
14 divided by 6 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 106542.0
Subtracting 12 from 14 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 6 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 106542.3
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 6, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 106542.33
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 106542.33, with a leftover of 0.002.
