We look at the division of 774859 by 30 
The aim is to understand the frequency of 30 in 774859.

Advancing 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
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 30

Let's proceed to step 2:
The number 30 fits into 77 2 times, leaving a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 17 after subtracting 60 from 77.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 30

Let's proceed to step 3:
30 goes into 174 5 times with a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 24 after subtracting 150 from 174.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 30

Going ahead to step 4:
The number 30 fits into 248 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 258.0
If we subtract 240 from 248, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 30

Step 5:
If we divide 85 by 30, we get 2 and a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2582.0
Deduct 60 from 85 and we're left with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 30

Moving on to step 6:
The number 30 fits into 259 8 times, leaving a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 25828.0
If we take 240 away from 259, 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.

Advancing to step 7:
30 can be fit into 190 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 25828.6
Deduct 180 from 190 and we're left 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.

Step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 25828.63
Subtracting 90 from 100 leaves us 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 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: 25828.633
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.

Our division results in 25828.633 with a remaining 0.001.
