518966 ÷ 66 
We're looking to find how many times 66 goes into 518966.

Advancing to step 1:
If we divide 5 by 66, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 66

On to step 2:
66 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 66

Step 3:
When dividing 518 by 66, we get 7 with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 462 from 518, we get 56.
Append the next digit (9) from the dividend to 56 and continue with: 569 / 66

Let's proceed to step 4:
66 can be fit into 569 8 times, resulting in a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 78.0
The remainder is 41 after subtracting 528 from 569.
Include the next digit (6) from the dividend after 41, then repeat: 416 / 66

Going ahead to step 5:
The number 66 fits into 416 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 786.0
The remainder is 20 after subtracting 396 from 416.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 66

On to step 6:
66 goes into 206 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 7863.0
The remainder is 8 after subtracting 198 from 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 7863.1
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
When dividing 140 by 66, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 7863.12
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
66 can be fit into 80 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 7863.121
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
140 divided by 66 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 7863.1212
Deduct 132 from 140 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
66 can be fit into 80 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 7863.12121
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
140 divided by 66 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 7863.121212
If we take 132 away from 140, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
66 goes into 80 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 7863.1212121
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
When dividing 140 by 66, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 7863.12121212
Deduct 132 from 140 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 7863.12121212, with a leftover of 8e-09.
