840617 divided by 30 
Let's see how many times 30 fits into 840617.

On to step 1:
30 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 30

Let's proceed to step 2:
When dividing 84 by 30, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 60 from 84 and we're left with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 30

On to step 3:
30 can be fit into 240 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 240 from 240 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 30

Advancing to step 4:
If we divide 6 by 30, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 280.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 30

Going ahead to step 5:
30 goes into 61 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2802.0
The remainder is 1 after subtracting 60 from 61.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 30

Moving on to step 6:
17 divided by 30 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 28020.0
Subtracting 0 from 17 leaves us 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.

Moving on to step 7:
30 goes into 170 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 28020.5
Deduct 150 from 170 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.

Let's proceed 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: 28020.56
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.

On to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 28020.566
Deduct 180 from 200 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.

The final outcome is 28020.566, with a leftover of 0.002.
