We divide 878459 by 30
We want to figure out the number of times 878459 can be divided by 30.

Advancing to step 1:
30 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 30

Advancing to step 2:
The number 30 fits into 87 2 times, leaving a remainder of 27.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 60 from 87, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 30

Advancing to step 3:
If we divide 278 by 30, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 270 away from 278, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 30

Going ahead to step 4:
84 divided by 30 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 292.0
If we subtract 60 from 84, we get 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 30

On to step 5:
The number 30 fits into 245 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 2928.0
The remainder is 5 after subtracting 240 from 245.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 30

Step 6:
When dividing 59 by 30, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 29281.0
Subtract 30 from 59 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
30 can be fit into 290 9 times, resulting in a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 29281.9
Deduct 270 from 290 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.

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: 29281.96
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.

Moving on to step 9:
30 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 29281.966
Subtract 180 from 200 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.

After the division, we end up with 29281.966 and a remainder of 0.002.
