We're dividing 23161809 by 66 
Let's see how many times 66 fits into 23161809.

Moving on to step 1:
66 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 66

Step 2:
When dividing 23 by 66, we get 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 66

Going ahead to step 3:
When dividing 231 by 66, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 198 from 231 and we're left with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 66

Moving on to step 4:
The number 66 fits into 336 5 times, leaving a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 330 away from 336, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 66

Going ahead to step 5:
66 can be fit into 61 0 times, resulting in a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 350.0
If we subtract 0 from 61, we get 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 66

Advancing to step 6:
If we divide 618 by 66, we get 9 and a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 3509.0
If we subtract 594 from 618, we get 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 66

Let's proceed to step 7:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 35093.0
The remainder is 42 after subtracting 198 from 240.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 66

Going ahead to step 8:
429 divided by 66 is 6 with a remainder of 33.
The next digit of our result is 6. 
Result so far: 350936.0
The remainder is 33 after subtracting 396 from 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
330 divided by 66 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 350936.5
If we subtract 330 from 330, 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.

Step 10:
If we divide 0 by 66, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 350936.5
Subtract 0 from 0 to 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.

Moving on to step 11:
66 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 350936.5
Subtract 0 from 0 to 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 result is 350936.5 with a remainder of 0.0.
