We're dividing 501189 by 66 
We want to figure out the number of times 501189 can be divided by 66.

Let's proceed to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 66

On to step 2:
50 divided by 66 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 66

Step 3:
If we divide 501 by 66, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 462 from 501 to get 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 66

On to step 4:
66 goes into 391 5 times with a remainder of 61.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we subtract 330 from 391, we get 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 66

Moving on to step 5:
If we divide 618 by 66, we get 9 and a remainder of 24.
The next digit of our result is 9. 
Result so far: 759.0
If we take 594 away from 618, we end up with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 66

Going ahead to step 6:
66 goes into 249 3 times with a remainder of 51.
The next digit of our result is 3. 
Result so far: 7593.0
Deduct 198 from 249 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
If we divide 510 by 66, we get 7 and a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 7593.7
Subtracting 462 from 510 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
66 can be fit into 480 7 times, resulting in a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 7593.77
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 7593.77, with a leftover of 0.018.
