We're dividing 782644 by 30 
The aim is to understand the frequency of 30 in 782644.

Let's proceed to step 1:
If we divide 7 by 30, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 30

Moving on to step 2:
The number 30 fits into 78 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 60 from 78 leaves us with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 30

Step 3:
182 divided by 30 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 180 from 182 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 30

Going ahead to step 4:
30 goes into 26 0 times with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 30

Advancing to step 5:
If we divide 264 by 30, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 2608.0
Subtract 240 from 264 to get 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 30

Moving on to step 6:
30 goes into 244 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 26088.0
The remainder is 4 after subtracting 240 from 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
When dividing 40 by 30, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 26088.1
Subtract 30 from 40 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.

Step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 26088.13
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.

Advancing to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 26088.133
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.

The final result is 26088.133 with a remainder of 0.001.
