We divide 668663 by 66
We want to figure out the number of times 668663 can be divided by 66.

Let's proceed to step 1:
When dividing 6 by 66, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 66

Advancing to step 2:
The number 66 fits into 66 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 66 from 66 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 66

Going ahead to step 3:
66 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 66

Step 4:
66 can be fit into 86 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we subtract 66 from 86, we get 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 66

Going ahead to step 5:
The number 66 fits into 206 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 1013.0
Deduct 198 from 206 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 66

Let's proceed to step 6:
When dividing 83 by 66, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 10131.0
Subtract 66 from 83 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
If we divide 170 by 66, we get 2 and a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 10131.2
If we subtract 132 from 170, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
When dividing 380 by 66, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 10131.25
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
If we divide 500 by 66, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 10131.257
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
66 goes into 380 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 10131.2575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 66, we get 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 10131.25757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
If we divide 380 by 66, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 10131.257575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 10131.2575757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
If we divide 380 by 66, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 10131.25757575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 10131.25757575, with a leftover of 5e-08.
