Let's divide 668856 by 30
We're looking to find how many times 30 goes into 668856.

Let's proceed to 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
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 30

Going ahead to step 2:
If we divide 66 by 30, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 60 from 66 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 30

Going ahead to step 3:
The number 30 fits into 68 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 60 away from 68, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 30

Advancing to step 4:
If we divide 88 by 30, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 222.0
If we subtract 60 from 88, we get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 30

On to step 5:
285 divided by 30 is 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 2229.0
Deduct 270 from 285 and we're left with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 30

Let's proceed to step 6:
30 can be fit into 156 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 22295.0
Subtract 150 from 156 to 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.

Going ahead to step 7:
30 can be fit into 60 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 22295.2
Deduct 60 from 60 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.

On to step 8:
If we divide 0 by 30, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22295.2
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.

Let's proceed to step 9:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22295.2
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.

The final outcome is 22295.2, with a leftover of 0.0.
