806575 divided by 66 
Our goal is to divide 806575 by 66.

Going ahead to step 1:
8 divided by 66 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 66

On to step 2:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 66 from 80 to get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 66

Advancing to step 3:
146 divided by 66 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 132 from 146, we get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 66

Moving on to step 4:
66 can be fit into 145 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we take 132 away from 145, we end up with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 66

On to step 5:
If we divide 137 by 66, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 1222.0
If we subtract 132 from 137, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 66

Moving on to step 6:
The number 66 fits into 55 0 times, leaving a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 12220.0
If we take 0 away from 55, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
If we divide 550 by 66, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 12220.8
If we subtract 528 from 550, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
If we divide 220 by 66, we get 3 and a remainder of 22.
The next digit of our result is 3. 
Result so far: 12220.83
If we subtract 198 from 220, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
66 goes into 220 3 times with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 12220.833
The remainder is 22 after subtracting 198 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 12220.833 with a remainder of 0.0022.
