We're dividing 512007 by 66 
Let's see how many times 66 fits into 512007.

Going ahead to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 66

Step 2:
The number 66 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 66

Going ahead to step 3:
66 goes into 512 7 times with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 462 from 512 and we're left with 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 66

Let's proceed to step 4:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtract 462 from 500 to get 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 66

Going ahead to step 5:
380 divided by 66 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 775.0
Deduct 330 from 380 and we're left with 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 66

Moving on to step 6:
The number 66 fits into 507 7 times, leaving a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 7757.0
If we take 462 away from 507, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
If we divide 450 by 66, we get 6 and a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 7757.6
Subtract 396 from 450 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
540 divided by 66 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 7757.68
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
66 goes into 120 1 times with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 7757.681
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
If we divide 540 by 66, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 7757.6818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
If we divide 120 by 66, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 7757.68181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
540 divided by 66 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 7757.681818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
120 divided by 66 is 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 7757.6818181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 14:
66 goes into 540 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 7757.68181818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 7757.68181818 with a balance of 1.2e-08.
