We look at the division of 781519 by 30 
We want to figure out the number of times 781519 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.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 30

Moving on to step 2:
If we divide 78 by 30, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 60 from 78 to get 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 30

Step 3:
181 divided by 30 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we subtract 180 from 181, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 30

Step 4:
The number 30 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 260.0
If we take 0 away from 15, we end up with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 30

Going ahead to step 5:
30 can be fit into 151 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 2605.0
The remainder is 1 after subtracting 150 from 151.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 30

Moving on to step 6:
If we divide 19 by 30, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 26050.0
Subtract 0 from 19 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
30 can be fit into 190 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 26050.6
If we take 180 away from 190, 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.

Advancing to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 26050.63
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.

Let's proceed to step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 26050.633
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.

In conclusion, the division gives 26050.633 with a balance of 0.001.
