29431 divided by 30 
The aim is to understand the frequency of 30 in 29431.

On to step 1:
The number 30 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 30

Step 2:
The number 30 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 30

Step 3:
294 divided by 30 is 9 with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 24 after subtracting 270 from 294.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 30

Going ahead to step 4:
243 divided by 30 is 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 98.0
Deduct 240 from 243 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 30

Let's proceed to step 5:
The number 30 fits into 31 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 981.0
Subtract 30 from 31 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
30 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 981.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 981.03
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 981.033
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 981.033 with a balance of 0.001.
