Let's divide 668581 by 30
We're looking to find how many times 30 goes into 668581.

Step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 30

Step 2:
30 can be fit into 66 2 times, resulting in 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.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 30

Going ahead to step 3:
When dividing 68 by 30, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 60 away from 68, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 30

Step 4:
If we divide 85 by 30, we get 2 and a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 222.0
If we subtract 60 from 85, we get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 30

Advancing to step 5:
30 goes into 258 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 2228.0
If we subtract 240 from 258, we get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 30

Advancing to step 6:
30 can be fit into 181 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 22286.0
Subtracting 180 from 181 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 30 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 22286.0
Subtracting 0 from 10 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.

Advancing to step 8:
100 divided by 30 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 22286.03
If we take 90 away from 100, we end up 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 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 22286.033
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.

Our division results in 22286.033 with a remaining 0.001.
