We divide 666117 by 9
We want to figure out the number of times 666117 can be divided by 9.

On to step 1:
9 can be fit into 6 0 times, resulting in 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.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 9

Advancing to step 2:
9 goes into 66 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 63 from 66, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 9

Step 3:
When dividing 36 by 9, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 74.0
If we take 36 away from 36, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 9

Step 4:
If we divide 1 by 9, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 740.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 9

Moving on to step 5:
9 can be fit into 11 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 7401.0
The remainder is 2 after subtracting 9 from 11.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 9

On to step 6:
9 can be fit into 27 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 74013.0
The remainder is 0 after subtracting 27 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 9 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 74013.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 9 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 74013.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 74013.0, with a leftover of 0.0.
