665930 ÷ 66 
Let's see how many times 66 fits into 665930.

On to step 1:
When dividing 6 by 66, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 66

Let's proceed to step 2:
66 can be fit into 66 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 66 away from 66, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 66

Going ahead to step 3:
5 divided by 66 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 66

Advancing to step 4:
59 divided by 66 is 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we subtract 0 from 59, we get 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 66

Going ahead to step 5:
66 can be fit into 593 8 times, resulting in a remainder of 65.
The number 8 becomes the next digit in our result. 
Result so far: 1008.0
Deduct 528 from 593 and we're left with 65.
Include the next digit (0) from the dividend after 65, then repeat: 650 / 66

Let's proceed to step 6:
66 goes into 650 9 times with a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 10089.0
Deduct 594 from 650 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
If we divide 560 by 66, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 10089.8
Subtracting 528 from 560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
66 goes into 320 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 10089.84
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
66 goes into 560 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 10089.848
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
66 can be fit into 320 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 10089.8484
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
66 can be fit into 560 8 times, resulting in a remainder of 32.
The next digit of our result is 8. 
Result so far: 10089.84848
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
The number 66 fits into 320 4 times, leaving a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 10089.848484
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
If we divide 560 by 66, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 10089.8484848
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
When dividing 320 by 66, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 10089.84848484
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 10089.84848484 with a remaining 5.6e-08.
