643246 ÷ 6 
Let's see how many times 6 fits into 643246.

Moving on to step 1:
The number 6 fits into 6 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 6 from 6, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 6

Moving on to step 2:
When dividing 4 by 6, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 6

On to step 3:
When dividing 43 by 6, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Subtract 42 from 43 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 6

Step 4:
The number 6 fits into 12 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 1072.0
Subtracting 12 from 12 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 6

Let's proceed to step 5:
When dividing 4 by 6, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 10720.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 6

Advancing to step 6:
If we divide 46 by 6, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 107207.0
Deduct 42 from 46 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.

Step 7:
40 divided by 6 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 107207.6
Deduct 36 from 40 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.

Advancing to step 8:
When dividing 40 by 6, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 107207.66
Subtracting 36 from 40 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.

The final result is 107207.66 with a remainder of 0.004.
