Let's divide 2808184 by 30
The aim is to understand the frequency of 30 in 2808184.

Advancing to step 1:
If we divide 2 by 30, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 30

Advancing to step 2:
When dividing 28 by 30, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 30

Going ahead to step 3:
280 divided by 30 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 270 from 280 and we're left with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 30

Let's proceed to step 4:
If we divide 108 by 30, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtract 90 from 108 to get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 30

Going ahead to step 5:
30 goes into 181 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 936.0
The remainder is 1 after subtracting 180 from 181.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 30

Going ahead to step 6:
18 divided by 30 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 9360.0
Subtract 0 from 18 to get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 30

Let's proceed to step 7:
If we divide 184 by 30, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 93606.0
Subtracting 180 from 184 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 30, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 93606.1
Subtract 30 from 40 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.

On to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 93606.13
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 93606.133
If we subtract 90 from 100, we 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.

The final result is 93606.133 with a remainder of 0.001.
