Let's divide 643689 by 6
Let's see how many times 6 fits into 643689.

Let's proceed to 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
If we take 6 away from 6, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 6

Moving on to step 2:
4 divided by 6 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 6

On to step 3:
43 divided by 6 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we subtract 42 from 43, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 6

On to step 4:
The number 6 fits into 16 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1072.0
Subtracting 12 from 16 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 6

Step 5:
When dividing 48 by 6, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 10728.0
If we subtract 48 from 48, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 6

Step 6:
9 divided by 6 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 107281.0
If we subtract 6 from 9, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
6 goes into 30 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 107281.5
Subtract 30 from 30 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 6, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 107281.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 6 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 107281.5
If we subtract 0 from 0, we 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 107281.5 with a balance of 0.0.
