665530 divided by 9 
Our goal is to divide 665530 by 9.

Step 1:
6 divided by 9 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 9

Advancing to step 2:
The number 9 fits into 66 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 63 from 66 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 9

Moving on to step 3:
9 can be fit into 35 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 8 after subtracting 27 from 35.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 9

Moving on to step 4:
When dividing 85 by 9, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 739.0
If we subtract 81 from 85, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 9

On to step 5:
43 divided by 9 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 7394.0
The remainder is 7 after subtracting 36 from 43.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 9

Going ahead to step 6:
If we divide 70 by 9, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 73947.0
If we subtract 63 from 70, we get 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 7:
The number 9 fits into 70 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 73947.7
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
9 goes into 70 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 73947.77
If we take 63 away from 70, we end up 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.

The final outcome is 73947.77, with a leftover of 0.007.
