Let's divide 813948 by 30
We're looking to find how many times 30 goes into 813948.

On to step 1:
30 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 30

Moving on to step 2:
If we divide 81 by 30, we get 2 and a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 60 away from 81, we end up with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 30

Going ahead to step 3:
When dividing 213 by 30, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 210 from 213 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 30

Advancing to step 4:
The number 30 fits into 39 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 271.0
Subtract 30 from 39 to get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 30

Moving on to step 5:
The number 30 fits into 94 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 2713.0
Deduct 90 from 94 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 30

On to step 6:
When dividing 48 by 30, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 27131.0
If we subtract 30 from 48, 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:
If we divide 180 by 30, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 27131.6
The remainder is 0 after subtracting 180 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 27131.6
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.

Let's proceed to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 27131.6
Subtracting 0 from 0 leaves us 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.

Our division results in 27131.6 with a remaining 0.0.
