Let's divide 485287 by 30
Let's see how many times 30 fits into 485287.

Moving on to step 1:
If we divide 4 by 30, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 30

Going ahead to step 2:
48 divided by 30 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
If we take 30 away from 48, we end up with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 30

On to step 3:
185 divided by 30 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 5 after subtracting 180 from 185.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 30

On to step 4:
52 divided by 30 is 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
If we take 30 away from 52, we end up with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 30

Moving on to step 5:
228 divided by 30 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 1617.0
Subtract 210 from 228 to get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 30

Let's proceed to step 6:
30 goes into 187 6 times with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 16176.0
Subtracting 180 from 187 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
30 can be fit into 70 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 16176.2
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
30 goes into 100 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 16176.23
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 16176.233
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 16176.233 with a balance of 0.001.
