19390 divided by 30 
We're looking to find how many times 30 goes into 19390.

Let's proceed to step 1:
1 divided by 30 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 30

Let's proceed to step 2:
30 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 30

Going ahead to step 3:
30 goes into 193 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 180 from 193, we get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 30

Let's proceed to step 4:
139 divided by 30 is 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 120 from 139, we get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 30

Going ahead to step 5:
30 goes into 190 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 646.0
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 6:
When dividing 100 by 30, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 646.3
If we take 90 away from 100, 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.

On to step 7:
30 goes into 100 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 646.33
Deduct 90 from 100 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.

Our division results in 646.33 with a remaining 0.01.
