508891 ÷ 66 
We want to figure out the number of times 508891 can be divided by 66.

Going ahead to step 1:
66 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 66

Moving on to step 2:
The number 66 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 66

On to step 3:
The number 66 fits into 508 7 times, leaving a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 462 away from 508, we end up with 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 66

On to step 4:
The number 66 fits into 468 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 77.0
The remainder is 6 after subtracting 462 from 468.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 66

Step 5:
When dividing 69 by 66, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 771.0
If we subtract 66 from 69, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 66

Let's proceed to step 6:
If we divide 31 by 66, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 7710.0
Subtracting 0 from 31 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
If we divide 310 by 66, we get 4 and a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 7710.4
Subtract 264 from 310 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
If we divide 460 by 66, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 7710.46
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
640 divided by 66 is 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 7710.469
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
The number 66 fits into 460 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 7710.4696
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
640 divided by 66 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 7710.46969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
If we divide 460 by 66, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 7710.469696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
640 divided by 66 is 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 7710.4696969
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 7710.46969696
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 7710.46969696, with a leftover of 6.4e-08.
