We divide 643020 by 6
We're looking to find how many times 6 goes into 643020.

On to step 1:
The number 6 fits into 6 1 times, leaving 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.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 6

Let's proceed to step 2:
When dividing 4 by 6, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
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:
The number 6 fits into 43 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 107.0
The remainder is 1 after subtracting 42 from 43.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 6

On to step 4:
If we divide 10 by 6, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1071.0
The remainder is 4 after subtracting 6 from 10.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 6

Going ahead to step 5:
The number 6 fits into 42 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 10717.0
If we subtract 42 from 42, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 6

On to step 6:
When dividing 0 by 6, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 107170.0
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.

Step 7:
6 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 107170.0
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.

Going ahead to step 8:
0 divided by 6 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 107170.0
Subtracting 0 from 0 leaves us 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.

Our division results in 107170.0 with a remaining 0.0.
