872664 divided by 66 
Let's see how many times 66 fits into 872664.

Step 1:
8 divided by 66 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 66

Advancing to step 2:
When dividing 87 by 66, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 66 from 87 to get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 66

Going ahead to step 3:
66 goes into 212 3 times with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 198 from 212 and we're left with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 66

Let's proceed to step 4:
146 divided by 66 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Subtract 132 from 146 to get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 66

Going ahead to step 5:
When dividing 146 by 66, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1322.0
The remainder is 14 after subtracting 132 from 146.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 66

Moving on to step 6:
66 goes into 144 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 13222.0
Subtract 132 from 144 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
If we divide 120 by 66, we get 1 and a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 13222.1
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 8:
66 goes into 540 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 13222.18
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 66 is 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 13222.181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
66 can be fit into 540 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 13222.1818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
The number 66 fits into 120 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 13222.18181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 13222.181818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
When dividing 120 by 66, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 13222.1818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 14:
When dividing 540 by 66, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 13222.18181818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 13222.18181818, with a leftover of 1.2e-08.
