We look at the division of 66572797 by 30 
Let's see how many times 30 fits into 66572797.

Step 1:
6 divided by 30 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 30

Step 2:
66 divided by 30 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 60 away from 66, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 30

Advancing to step 3:
65 divided by 30 is 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 60 away from 65, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 30

Going ahead to step 4:
The number 30 fits into 57 1 times, leaving a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Subtracting 30 from 57 leaves us with 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 30

Moving on to step 5:
30 can be fit into 272 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 2219.0
The remainder is 2 after subtracting 270 from 272.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 30

Advancing to step 6:
The number 30 fits into 27 0 times, leaving a remainder of 27.
The next digit of our result is 0. 
Result so far: 22190.0
If we take 0 away from 27, we end up with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 30

Going ahead to step 7:
30 goes into 279 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 221909.0
The remainder is 9 after subtracting 270 from 279.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 30

Advancing to step 8:
30 can be fit into 97 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 2219093.0
If we subtract 90 from 97, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
30 can be fit into 70 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2219093.2
Deduct 60 from 70 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
100 divided by 30 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 2219093.23
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 2219093.233
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 2219093.233, and the remainder is 0.001.
