894399 ÷ 30 
The aim is to understand the frequency of 30 in 894399.

Step 1:
When dividing 8 by 30, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 30

Going ahead to step 2:
The number 30 fits into 89 2 times, leaving a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 29 after subtracting 60 from 89.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 30

Let's proceed to step 3:
30 goes into 294 9 times with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 270 from 294, we get 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 30

Let's proceed to step 4:
243 divided by 30 is 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 298.0
Subtract 240 from 243 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 30

On to step 5:
If we divide 39 by 30, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 2981.0
Deduct 30 from 39 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 30

Moving on to step 6:
When dividing 99 by 30, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 29813.0
If we subtract 90 from 99, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
30 goes into 90 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 29813.3
Deduct 90 from 90 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.

Let's proceed to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 29813.3
If we subtract 0 from 0, 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.

Let's proceed to step 9:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 29813.3
Subtract 0 from 0 to 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.

The final result is 29813.3 with a remainder of 0.0.
