We look at the division of 518687 by 66 
We want to divide 518687 by 66.

Advancing to step 1:
66 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 66

Advancing to step 2:
66 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 66

Step 3:
66 goes into 518 7 times with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 56 after subtracting 462 from 518.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 66

Going ahead to step 4:
When dividing 566 by 66, we get 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 78.0
The remainder is 38 after subtracting 528 from 566.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 66

Let's proceed to step 5:
66 goes into 388 5 times with a remainder of 58.
Write down 5 as next digit of the result. 
Result so far: 785.0
If we subtract 330 from 388, we get 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 66

Moving on to step 6:
587 divided by 66 is 8 with a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 7858.0
Deduct 528 from 587 and we're left 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.

Going ahead to step 7:
66 goes into 590 8 times with a remainder of 62.
The next digit of our result is 8. 
Result so far: 7858.8
The remainder is 62 after subtracting 528 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 7858.89
Subtracting 594 from 620 leaves us with 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 9:
260 divided by 66 is 3 with a remainder of 62.
The next digit of our result is 3. 
Result so far: 7858.893
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
If we divide 620 by 66, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 7858.8939
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
The number 66 fits into 260 3 times, leaving a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 7858.89393
Subtract 198 from 260 to 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.

Let's proceed to step 12:
If we divide 620 by 66, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 7858.893939
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:
66 goes into 260 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 7858.8939393
Deduct 198 from 260 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.

Advancing to step 14:
66 goes into 620 9 times with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 7858.89393939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 7858.89393939 with a balance of 2.6e-08.
