We divide 660412 by 9
Let's see how many times 9 fits into 660412.

Step 1:
The number 9 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 9

Step 2:
9 goes into 66 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 63 from 66 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 9

Going ahead to step 3:
30 divided by 9 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtracting 27 from 30 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 9

Step 4:
9 goes into 34 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 733.0
The remainder is 7 after subtracting 27 from 34.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 9

Let's proceed to step 5:
71 divided by 9 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 7337.0
Deduct 63 from 71 and we're left with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 9

Going ahead to step 6:
82 divided by 9 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 73379.0
Subtracting 81 from 82 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 9, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 73379.1
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
When dividing 10 by 9, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 73379.11
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 73379.11 with a remainder of 0.001.
