784039 divided by 30 
The aim is to understand the frequency of 30 in 784039.

Moving on to step 1:
30 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 30

Going ahead to step 2:
The number 30 fits into 78 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 60 from 78 to get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 30

Moving on to step 3:
184 divided by 30 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 4 after subtracting 180 from 184.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 30

Let's proceed to step 4:
The number 30 fits into 40 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 261.0
The remainder is 10 after subtracting 30 from 40.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 30

Moving on to step 5:
The number 30 fits into 103 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 2613.0
If we subtract 90 from 103, we get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 30

Let's proceed to step 6:
30 can be fit into 139 4 times, resulting in a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 26134.0
If we take 120 away from 139, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
190 divided by 30 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 26134.6
Subtract 180 from 190 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 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 26134.63
If we subtract 90 from 100, we 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.

Advancing to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 26134.633
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.

The quotient of the division is 26134.633, and the remainder is 0.001.
