130238 ÷ 30 
The aim is to understand the frequency of 30 in 130238.

Moving on to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 30

Advancing to step 2:
13 divided by 30 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 30

On to step 3:
30 goes into 130 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 120 from 130 leaves us with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 30

On to step 4:
102 divided by 30 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we take 90 away from 102, we end up with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 30

Advancing to step 5:
123 divided by 30 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
If we subtract 120 from 123, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 30

On to step 6:
The number 30 fits into 38 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 4341.0
Subtracting 30 from 38 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
80 divided by 30 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 4341.2
Deduct 60 from 80 and we're left 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.

Moving on to step 8:
30 goes into 200 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 4341.26
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:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 4341.266
Subtracting 180 from 200 leaves us 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.

The final outcome is 4341.266, with a leftover of 0.002.
