We look at the division of 408851 by 30 
We want to divide 408851 by 30.

Step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 30

Advancing to step 2:
40 divided by 30 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 30 from 40, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 30

Advancing to step 3:
108 divided by 30 is 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 90 from 108, we get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 30

Let's proceed to step 4:
When dividing 188 by 30, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 136.0
If we subtract 180 from 188, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 30

On to step 5:
85 divided by 30 is 2 with a remainder of 25.
The next digit of our result is 2. 
Result so far: 1362.0
If we subtract 60 from 85, we get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 30

Let's proceed to step 6:
30 can be fit into 251 8 times, resulting in a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 13628.0
Subtract 240 from 251 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
When dividing 110 by 30, we get 3 with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 13628.3
The remainder is 20 after subtracting 90 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 13628.36
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.

Advancing to step 9:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 13628.366
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.

The quotient of the division is 13628.366, and the remainder is 0.002.
