We divide 491780 by 30
We want to figure out the number of times 491780 can be divided by 30.

Advancing to step 1:
The number 30 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 30

Going ahead to step 2:
49 divided by 30 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 30 from 49 leaves us with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 30

Step 3:
The number 30 fits into 191 6 times, leaving a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 180 away from 191, we end up with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 30

Going ahead to step 4:
If we divide 117 by 30, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
Subtracting 90 from 117 leaves us with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 30

Going ahead to step 5:
When dividing 278 by 30, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 1639.0
Subtract 270 from 278 to get 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.
Put 2 as the next digit of the answer. 
Result so far: 16392.0
If we subtract 60 from 80, 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.

Step 7:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 16392.6
Subtracting 180 from 200 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 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 16392.66
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.

The quotient of the division is 16392.66, and the remainder is 0.02.
