604398 divided by 30 
Let's see how many times 30 fits into 604398.

Moving on to step 1:
6 divided by 30 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 30

Going ahead to step 2:
If we divide 60 by 30, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 60 from 60, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 30

Advancing to step 3:
4 divided by 30 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 4 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 30

Moving on to step 4:
30 goes into 43 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 201.0
Subtracting 30 from 43 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 30

Going ahead to step 5:
30 goes into 139 4 times with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 2014.0
Subtracting 120 from 139 leaves us with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 30

Moving on to step 6:
30 goes into 198 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 20146.0
If we subtract 180 from 198, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
30 goes into 180 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 20146.6
If we take 180 away from 180, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20146.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20146.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 20146.6 and a remainder of 0.0.
