We're dividing 621004 by 6 
Let's see how many times 6 fits into 621004.

Moving on to step 1:
If we divide 6 by 6, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 6

Let's proceed to step 2:
If we divide 2 by 6, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 6

Let's proceed to step 3:
The number 6 fits into 21 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 103.0
If we subtract 18 from 21, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 6

Let's proceed to step 4:
The number 6 fits into 30 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1035.0
If we take 30 away from 30, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 6

On to step 5:
The number 6 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10350.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 6

Step 6:
6 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 103500.0
Subtract 0 from 4 to 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.

Step 7:
6 goes into 40 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 103500.6
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.

Let's proceed to step 8:
6 goes into 40 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 103500.66
Subtract 36 from 40 to 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.

The final result is 103500.66 with a remainder of 0.004.
