We look at the division of 478874 by 30 
Let's see how many times 30 fits into 478874.

Going ahead to step 1:
4 divided by 30 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 30

Going ahead to step 2:
30 goes into 47 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 30 from 47, we get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 30

Going ahead to step 3:
178 divided by 30 is 5 with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 150 from 178 and we're left with 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 30

On to step 4:
The number 30 fits into 288 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 159.0
Subtracting 270 from 288 leaves us with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 30

Let's proceed to step 5:
187 divided by 30 is 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 1596.0
Subtracting 180 from 187 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 30

Step 6:
When dividing 74 by 30, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 15962.0
Subtract 60 from 74 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 30 fits into 140 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 15962.4
Deduct 120 from 140 and we're left 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:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 15962.46
Deduct 180 from 200 and we're left 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 9:
200 divided by 30 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 15962.466
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.

After the division, we end up with 15962.466 and a remainder of 0.002.
