812887 ÷ 30 
Our goal is to divide 812887 by 30.

On to step 1:
8 divided by 30 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 30

Let's proceed to step 2:
When dividing 81 by 30, we get 2 with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 60 from 81 and we're left with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 30

Advancing to step 3:
30 can be fit into 212 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtracting 210 from 212 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 30

Let's proceed to step 4:
28 divided by 30 is 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 270.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 30

Let's proceed to step 5:
If we divide 288 by 30, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 2709.0
If we take 270 away from 288, we end up with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 30

On to step 6:
187 divided by 30 is 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 27096.0
If we subtract 180 from 187, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
30 can be fit into 70 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 27096.2
If we subtract 60 from 70, 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.

On to step 8:
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: 27096.23
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.

Going ahead 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: 27096.233
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.

The final result is 27096.233 with a remainder of 0.001.
