We look at the division of 660319 by 9 
We want to divide 660319 by 9.

Step 1:
When dividing 6 by 9, we get 0 with 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.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 9

Let's proceed to step 2:
The number 9 fits into 66 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
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

Moving on to step 3:
If we divide 30 by 9, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we take 27 away from 30, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 9

Step 4:
If we divide 33 by 9, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 733.0
If we take 27 away from 33, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 9

Let's proceed to step 5:
The number 9 fits into 61 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 7336.0
Subtracting 54 from 61 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 9

Going ahead to step 6:
9 goes into 79 8 times with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 73368.0
Subtracting 72 from 79 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
The number 9 fits into 70 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 73368.7
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
When dividing 70 by 9, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 73368.77
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 73368.77, with a leftover of 0.007.
