630385 ÷ 30 
Let's see how many times 30 fits into 630385.

Going ahead to step 1:
30 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 30

Moving on to step 2:
The number 30 fits into 63 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 60 from 63 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 30

Moving on to step 3:
30 can be fit into 30 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 30 from 30 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 30

Moving on to step 4:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 210.0
If we subtract 0 from 3, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 30

On to step 5:
30 goes into 38 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 2101.0
Deduct 30 from 38 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 30

Moving on to step 6:
The number 30 fits into 85 2 times, leaving a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 21012.0
Deduct 60 from 85 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
30 can be fit into 250 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 21012.8
Deduct 240 from 250 and we're left 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.

Advancing to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 21012.83
If we subtract 90 from 100, we 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.

Let's proceed to step 9:
30 goes into 100 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 21012.833
If we subtract 90 from 100, we 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 final result is 21012.833 with a remainder of 0.001.
