We're dividing 430400 by 6 
We want to divide 430400 by 6.

Going ahead to step 1:
When dividing 4 by 6, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 6

Step 2:
When dividing 43 by 6, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 42 from 43, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 6

Step 3:
6 can be fit into 10 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 71.0
The remainder is 4 after subtracting 6 from 10.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 6

On to step 4:
The number 6 fits into 44 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 717.0
If we subtract 42 from 44, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 6

Going ahead to step 5:
20 divided by 6 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 7173.0
The remainder is 2 after subtracting 18 from 20.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 6

On to step 6:
6 goes into 20 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 71733.0
Subtracting 18 from 20 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.

Step 7:
If we divide 20 by 6, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 71733.3
Subtracting 18 from 20 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.

Going ahead to step 8:
6 can be fit into 20 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 71733.33
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 71733.33 with a remaining 0.002.
