Let's divide 653709 by 30
The aim is to understand the frequency of 30 in 653709.

Step 1:
When dividing 6 by 30, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 30

Step 2:
30 goes into 65 2 times with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 5 after subtracting 60 from 65.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 30

Moving on to step 3:
When dividing 53 by 30, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 23 after subtracting 30 from 53.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 30

Moving on to step 4:
If we divide 237 by 30, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
If we subtract 210 from 237, we get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 30

Step 5:
The number 30 fits into 270 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 2179.0
If we take 270 away from 270, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 30

On to step 6:
30 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 21790.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 30, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 21790.3
Subtracting 90 from 90 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.

Going ahead to step 8:
If we divide 0 by 30, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21790.3
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21790.3
If we subtract 0 from 0, we get 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 21790.3 and a remainder of 0.0.
