612604 divided by 30 
Let's see how many times 30 fits into 612604.

Let's proceed to step 1:
If we divide 6 by 30, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 30

On to step 2:
When dividing 61 by 30, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 60 from 61, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 30

Advancing to step 3:
When dividing 12 by 30, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 12 to get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 30

On to step 4:
126 divided by 30 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Deduct 120 from 126 and we're left with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 30

Step 5:
30 goes into 60 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2042.0
The remainder is 0 after subtracting 60 from 60.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 30

On to step 6:
30 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 20420.0
Subtracting 0 from 4 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
When dividing 40 by 30, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 20420.1
Subtracting 30 from 40 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.

Advancing to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 20420.13
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.

Let's proceed to step 9:
100 divided by 30 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 20420.133
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.

Our division results in 20420.133 with a remaining 0.001.
