Let's divide 850294 by 30
We're looking to find how many times 30 goes into 850294.

Advancing to step 1:
The number 30 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 30

Going ahead to step 2:
If we divide 85 by 30, we get 2 and a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 60 from 85 leaves us with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 30

Moving on to step 3:
When dividing 250 by 30, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 240 away from 250, we end up with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 30

On to step 4:
30 can be fit into 102 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 283.0
Subtract 90 from 102 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 30

On to step 5:
30 can be fit into 129 4 times, resulting in a remainder of 9.
The next digit of our result is 4. 
Result so far: 2834.0
If we take 120 away from 129, we end up with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 30

Advancing to step 6:
94 divided by 30 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 28343.0
Deduct 90 from 94 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 30 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 28343.1
If we subtract 30 from 40, 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:
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: 28343.13
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.

Step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 28343.133
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 result is 28343.133 with a remainder of 0.001.
