668886 ÷ 30 
We're looking to find how many times 30 goes into 668886.

Going ahead to step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 30

Step 2:
The number 30 fits into 66 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 60 away from 66, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 30

On to step 3:
68 divided by 30 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 60 away from 68, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 30

On to step 4:
30 goes into 88 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 222.0
The remainder is 28 after subtracting 60 from 88.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 30

Let's proceed to step 5:
288 divided by 30 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 2229.0
The remainder is 18 after subtracting 270 from 288.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 30

Advancing to step 6:
When dividing 186 by 30, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 22296.0
If we subtract 180 from 186, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
30 goes into 60 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 22296.2
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22296.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 30 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22296.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 22296.2 and a remainder of 0.0.
