We look at the division of 869903 by 30 
We want to figure out the number of times 869903 can be divided by 30.

Step 1:
The number 30 fits into 8 0 times, leaving 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.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 30

Going ahead to step 2:
30 can be fit into 86 2 times, resulting in a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 26 after subtracting 60 from 86.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 30

On to step 3:
30 can be fit into 269 8 times, resulting in a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 29 after subtracting 240 from 269.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 30

Let's proceed to step 4:
The number 30 fits into 299 9 times, leaving a remainder of 29.
The next digit of our result is 9. 
Result so far: 289.0
Deduct 270 from 299 and we're left with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 30

Going ahead to step 5:
290 divided by 30 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 2899.0
If we take 270 away from 290, we end up with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 30

Going ahead to step 6:
30 can be fit into 203 6 times, resulting in a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 28996.0
Subtract 180 from 203 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
30 can be fit into 230 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 28996.7
Deduct 210 from 230 and we're left 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.

On to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 28996.76
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:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 28996.766
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 28996.766 with a balance of 0.002.
