We divide 852538 by 30
We want to figure out the number of times 852538 can be divided by 30.

On to step 1:
30 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 30

Going ahead to step 2:
The number 30 fits into 85 2 times, leaving a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 60 away from 85, we end up with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 30

Step 3:
When dividing 252 by 30, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 240 from 252, we get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 30

Moving on to step 4:
30 can be fit into 125 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 284.0
Subtracting 120 from 125 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 30

Going ahead to step 5:
The number 30 fits into 53 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 2841.0
Deduct 30 from 53 and we're left with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 30

Moving on to step 6:
If we divide 238 by 30, we get 7 and a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 28417.0
If we subtract 210 from 238, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
When dividing 280 by 30, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 28417.9
Subtract 270 from 280 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.

Moving on to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 28417.93
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.

Step 9:
30 goes into 100 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 28417.933
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.

The final result is 28417.933 with a remainder of 0.001.
