Let's divide 945717 by 30
The aim is to understand the frequency of 30 in 945717.

Step 1:
The number 30 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 30

Moving on to step 2:
94 divided by 30 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 90 from 94, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 30

Let's proceed to step 3:
30 goes into 45 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 30 away from 45, we end up with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 30

Let's proceed to step 4:
When dividing 157 by 30, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 315.0
If we take 150 away from 157, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 30

Moving on to step 5:
30 goes into 71 2 times with a remainder of 11.
The next digit of our result is 2. 
Result so far: 3152.0
If we subtract 60 from 71, we get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 30

Going ahead to step 6:
The number 30 fits into 117 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 31523.0
The remainder is 27 after subtracting 90 from 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
30 goes into 270 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 31523.9
The remainder is 0 after subtracting 270 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31523.9
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 30 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31523.9
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 31523.9 and a remainder of 0.0.
