Let's divide 813142 by 30
Let's see how many times 30 fits into 813142.

Moving on to step 1:
When dividing 8 by 30, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 30

Let's proceed to step 2:
30 can be fit into 81 2 times, resulting in a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 60 away from 81, we end up with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 30

On to step 3:
When dividing 213 by 30, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 210 away from 213, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 30

Advancing to step 4:
If we divide 31 by 30, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
Deduct 30 from 31 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 30

Step 5:
The number 30 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 2710.0
If we subtract 0 from 14, we get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 30

Moving on to step 6:
142 divided by 30 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 27104.0
Subtracting 120 from 142 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
If we divide 220 by 30, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 27104.7
Subtracting 210 from 220 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.

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: 27104.73
Subtracting 90 from 100 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 9:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 27104.733
The remainder is 10 after subtracting 90 from 100.
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 outcome is 27104.733, with a leftover of 0.001.
