We look at the division of 666310 by 66 
We want to figure out the number of times 666310 can be divided by 66.

On to step 1:
The number 66 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 66

Let's proceed to step 2:
66 can be fit into 66 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 66 from 66 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 66

Advancing to step 3:
The number 66 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 66

Advancing to step 4:
63 divided by 66 is 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 100.0
The remainder is 63 after subtracting 0 from 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 66

Advancing to step 5:
66 can be fit into 631 9 times, resulting in a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 1009.0
If we take 594 away from 631, we end up with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 66

Going ahead to step 6:
If we divide 370 by 66, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 10095.0
The remainder is 40 after subtracting 330 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
If we divide 400 by 66, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 10095.6
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 66, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10095.6
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
66 can be fit into 400 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 10095.606
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 66 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10095.606
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
66 goes into 400 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 10095.60606
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
66 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10095.60606
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
When dividing 400 by 66, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 10095.6060606
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
66 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10095.6060606
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 10095.6060606 and a remainder of 4e-08.
