We're dividing 781408 by 30 
We want to figure out the number of times 781408 can be divided by 30.

On to step 1:
If we divide 7 by 30, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 30

Moving on to step 2:
30 can be fit into 78 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 18 after subtracting 60 from 78.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 30

Going ahead to step 3:
If we divide 181 by 30, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 1 after subtracting 180 from 181.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 30

Step 4:
The number 30 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 260.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 30

Moving on to step 5:
30 can be fit into 140 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 2604.0
If we take 120 away from 140, we end up with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 30

Going ahead to step 6:
30 can be fit into 208 6 times, resulting in a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 26046.0
Deduct 180 from 208 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
When dividing 280 by 30, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 26046.9
If we take 270 away from 280, we end up 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.

Moving on to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 26046.93
Subtract 90 from 100 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 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 26046.933
If we take 90 away from 100, we end up 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.

Our division results in 26046.933 with a remaining 0.001.
