If we subtract 0 from 51, we get 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 66

Going ahead to step 3:
513 divided by 66 is 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 462 away from 513, we end up with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 66

Going ahead to step 4:
66 can be fit into 513 7 times, resulting in a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we subtract 462 from 513, we get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 66

Step 5:
If we divide 515 by 66, we get 7 and a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 777.0
If we take 462 away from 515, we end up with 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 66

Advancing to step 6:
The number 66 fits into 534 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 7778.0
Subtracting 528 from 534 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 66

Advancing to step 7:
The number 66 fits into 67 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 77781.0
The remainder is 1 after subtracting 66 from 67.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 66

Moving on to step 8:
66 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 777810.0
Subtracting 0 from 17 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
When dividing 170 by 66, we get 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 777810.2
If we take 132 away from 170, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 777810.25
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
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: 777810.257
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
66 can be fit into 380 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 777810.2575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
When dividing 500 by 66, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 777810.25757
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
66 goes into 380 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 777810.257575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 15:
66 can be fit into 500 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 777810.2575757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 16:
66 can be fit into 380 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 777810.25757575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.
