We look at the division of 813587 by 30 
We want to figure out the number of times 813587 can be divided by 30.

Going ahead to step 1:
30 goes into 8 0 times 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.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 30

Step 2:
The number 30 fits into 81 2 times, leaving a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 60 from 81 to get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 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
The remainder is 3 after subtracting 210 from 213.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 30

Advancing to step 4:
The number 30 fits into 35 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 271.0
If we take 30 away from 35, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 30

Moving on to step 5:
30 can be fit into 58 1 times, resulting in a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 2711.0
Subtract 30 from 58 to get 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 30

Going ahead to step 6:
When dividing 287 by 30, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 27119.0
If we take 270 away from 287, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
When dividing 170 by 30, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 27119.5
Subtract 150 from 170 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 27119.56
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 27119.566
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 27119.566 and a remainder of 0.002.
