146136 divided by 30 
The aim is to understand the frequency of 30 in 146136.

Let's proceed to step 1:
1 divided by 30 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 30

Moving on to step 2:
14 divided by 30 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 30

Step 3:
When dividing 146 by 30, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 120 from 146 and we're left with 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 30

Let's proceed to step 4:
The number 30 fits into 261 8 times, leaving a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we take 240 away from 261, we end up with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 30

Step 5:
30 can be fit into 213 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 487.0
Subtracting 210 from 213 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 30

Going ahead to step 6:
30 goes into 36 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 4871.0
If we subtract 30 from 36, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 30 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 4871.2
If we subtract 60 from 60, 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.

Step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4871.2
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.

Going ahead to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4871.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 4871.2 with a remainder of 0.0.
