We're dividing 820454 by 66 
We want to figure out the number of times 820454 can be divided by 66.

On to step 1:
When dividing 8 by 66, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 66

Moving on to step 2:
66 goes into 82 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 66 from 82 leaves us with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 66

Step 3:
160 divided by 66 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 132 away from 160, we end up with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 66

Step 4:
The number 66 fits into 284 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we take 264 away from 284, we end up with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 66

Step 5:
66 can be fit into 205 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 1243.0
The remainder is 7 after subtracting 198 from 205.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 66

Step 6:
The number 66 fits into 74 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 12431.0
Deduct 66 from 74 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 66, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 12431.1
If we subtract 66 from 80, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 66, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12431.12
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 66, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 12431.121
If we subtract 66 from 80, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
66 goes into 140 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 12431.1212
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 66, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 12431.12121
If we subtract 66 from 80, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
When dividing 140 by 66, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 12431.121212
If we take 132 away from 140, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
80 divided by 66 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 12431.1212121
Subtract 66 from 80 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
If we divide 140 by 66, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 12431.12121212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 12431.12121212, and the remainder is 8e-09.
