We're dividing 426722 by 30 
The aim is to understand the frequency of 30 in 426722.

On to step 1:
4 divided by 30 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 30

Going ahead to step 2:
30 can be fit into 42 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 30 from 42 and we're left with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 30

Moving on to step 3:
When dividing 126 by 30, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 6 after subtracting 120 from 126.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 30

Moving on to step 4:
67 divided by 30 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 142.0
If we subtract 60 from 67, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 30

Going ahead to step 5:
The number 30 fits into 72 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 1422.0
Subtracting 60 from 72 leaves us with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 30

Going ahead to step 6:
122 divided by 30 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 14224.0
Deduct 120 from 122 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
30 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 14224.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 14224.06
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 14224.066
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 14224.066 and a remainder of 0.002.
