We look at the division of 665403 by 9 
Let's see how many times 9 fits into 665403.

Step 1:
9 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 9

Going ahead to step 2:
The number 9 fits into 66 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 63 from 66 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 9

Advancing to step 3:
9 can be fit into 35 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtract 27 from 35 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 9

Let's proceed to step 4:
When dividing 84 by 9, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 739.0
Deduct 81 from 84 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 9

Going ahead to step 5:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 7393.0
If we subtract 27 from 30, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 9

Moving on to step 6:
9 can be fit into 33 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 73933.0
Subtract 27 from 33 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 9 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 73933.6
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
9 goes into 60 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 73933.66
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 73933.66 with a remaining 0.006.
