Let's divide 145017 by 66
Let's see how many times 66 fits into 145017.

On to step 1:
If we divide 1 by 66, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 66

On to step 2:
14 divided by 66 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 66

Going ahead to step 3:
66 goes into 145 2 times with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 132 away from 145, we end up with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 66

Step 4:
The number 66 fits into 130 1 times, leaving a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 66 from 130, we get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 66

Step 5:
66 goes into 641 9 times with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 219.0
If we take 594 away from 641, we end up with 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 66

On to step 6:
66 goes into 477 7 times with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 2197.0
The remainder is 15 after subtracting 462 from 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
If we divide 150 by 66, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2197.2
If we take 132 away from 150, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
66 can be fit into 180 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 2197.22
Subtracting 132 from 180 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.

Our division results in 2197.22 with a remaining 0.048.
