454638 divided by 30 
The aim is to understand the frequency of 30 in 454638.

Advancing to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 30

Let's proceed to step 2:
30 can be fit into 45 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 30 from 45 to get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 30

Advancing to step 3:
If we divide 154 by 30, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 4 after subtracting 150 from 154.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 30

Moving on to step 4:
If we divide 46 by 30, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 151.0
The remainder is 16 after subtracting 30 from 46.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 30

Going ahead to step 5:
If we divide 163 by 30, we get 5 and a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 1515.0
Deduct 150 from 163 and we're left with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 30

Advancing to step 6:
If we divide 138 by 30, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 15154.0
Subtract 120 from 138 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
180 divided by 30 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 15154.6
Subtract 180 from 180 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.

Moving on to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15154.6
Subtracting 0 from 0 leaves us 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.

Advancing to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15154.6
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.

Our division results in 15154.6 with a remaining 0.0.
