We look at the division of 487645 by 30 
We're looking to find how many times 30 goes into 487645.

Let's proceed to step 1:
30 goes into 4 0 times 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 (8) of the dividend behind the 4 and repeat the process: 48 / 30

Moving on to step 2:
If we divide 48 by 30, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 18 after subtracting 30 from 48.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 30

Going ahead to step 3:
If we divide 187 by 30, we get 6 and a remainder of 7.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 180 from 187, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 30

On to step 4:
30 can be fit into 76 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 162.0
If we subtract 60 from 76, we get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 30

Step 5:
30 goes into 164 5 times with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 1625.0
If we subtract 150 from 164, we get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 30

On to step 6:
If we divide 145 by 30, we get 4 and a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 16254.0
Subtract 120 from 145 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
30 can be fit into 250 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 16254.8
If we take 240 away from 250, we end up 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:
If we divide 100 by 30, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 16254.83
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 goes into 100 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 16254.833
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.

The quotient of the division is 16254.833, and the remainder is 0.001.
