We divide 510239 by 66
Our goal is to divide 510239 by 66.

Advancing to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left 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.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 66

Going ahead to step 3:
66 goes into 510 7 times with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 462 from 510, we get 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 66

Moving on to step 4:
When dividing 482 by 66, we get 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
The remainder is 20 after subtracting 462 from 482.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 66

Going ahead to step 5:
The number 66 fits into 203 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 773.0
If we subtract 198 from 203, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 66

Advancing to step 6:
The number 66 fits into 59 0 times, leaving a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 7730.0
Subtracting 0 from 59 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
590 divided by 66 is 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 7730.8
Deduct 528 from 590 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
When dividing 620 by 66, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 7730.89
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
260 divided by 66 is 3 with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 7730.893
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
When dividing 620 by 66, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 7730.8939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 7730.89393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
If we divide 620 by 66, we get 9 and a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 7730.893939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
260 divided by 66 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 7730.8939393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 14:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 7730.89393939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 7730.89393939, with a leftover of 2.6e-08.
