We divide 515775 by 66
We want to divide 515775 by 66.

On to step 1:
When dividing 5 by 66, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 66

On to step 2:
When dividing 51 by 66, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 66

Let's proceed to step 3:
When dividing 515 by 66, we get 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 462 from 515 to get 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 66

Advancing to step 4:
66 can be fit into 537 8 times, resulting in a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 528 from 537, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 66

Moving on to step 5:
66 goes into 97 1 times with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 781.0
If we subtract 66 from 97, we get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 66

Step 6:
66 goes into 315 4 times with a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 7814.0
Deduct 264 from 315 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
When dividing 510 by 66, we get 7 with a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 7814.7
Subtracting 462 from 510 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
480 divided by 66 is 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 7814.77
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 7814.77 with a balance of 0.018.
