We're dividing 818160 by 66 
Let's see how many times 66 fits into 818160.

Step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 66

Step 2:
81 divided by 66 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 15 after subtracting 66 from 81.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 66

On to step 3:
66 can be fit into 158 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 12.0
If we take 132 away from 158, we end up with 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 66

Going ahead to step 4:
66 can be fit into 261 3 times, resulting in a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we take 198 away from 261, we end up with 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 66

Let's proceed to step 5:
If we divide 636 by 66, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 1239.0
Deduct 594 from 636 and we're left with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 66

Step 6:
420 divided by 66 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 12396.0
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
When dividing 240 by 66, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 12396.3
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 12396.36
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
The number 66 fits into 240 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 12396.363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
If we divide 420 by 66, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 12396.3636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
If we divide 240 by 66, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 12396.36363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
If we divide 420 by 66, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 12396.363636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
If we divide 240 by 66, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 12396.3636363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
If we divide 420 by 66, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 12396.36363636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 12396.36363636 with a balance of 2.4e-08.
