We're dividing 456680 by 30 
We want to divide 456680 by 30.

Advancing to step 1:
If we divide 4 by 30, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 30

Advancing to step 2:
30 can be fit into 45 1 times, resulting in a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 30 from 45 leaves us with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 30

Advancing to step 3:
30 can be fit into 156 5 times, resulting in a remainder of 6.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 150 from 156, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 30

Step 4:
30 can be fit into 66 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Deduct 60 from 66 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 30

On to step 5:
68 divided by 30 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1522.0
Subtracting 60 from 68 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 30

Going ahead to step 6:
When dividing 80 by 30, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 15222.0
Subtracting 60 from 80 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 15222.6
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 15222.66
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 15222.66 with a remaining 0.02.
