236435 divided by 30 
The aim is to understand the frequency of 30 in 236435.

On to step 1:
The number 30 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 30

Going ahead to step 2:
23 divided by 30 is 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 30

Let's proceed to step 3:
The number 30 fits into 236 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 210 from 236 leaves us with 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 30

Advancing to step 4:
30 goes into 264 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 240 from 264 leaves us with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 30

On to step 5:
30 goes into 243 8 times with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 788.0
If we subtract 240 from 243, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 30

Moving on to step 6:
30 can be fit into 35 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 7881.0
Deduct 30 from 35 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 30, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 7881.1
Subtracting 30 from 50 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.

Let's proceed to step 8:
30 goes into 200 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 7881.16
Deduct 180 from 200 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.

On to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 7881.166
Deduct 180 from 200 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.

In conclusion, the division gives 7881.166 with a balance of 0.002.
