155479 divided by 30 
The aim is to understand the frequency of 30 in 155479.

Going ahead to step 1:
1 divided by 30 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 30

Let's proceed to step 2:
30 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 30

Let's proceed to step 3:
If we divide 155 by 30, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 150 from 155 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 30

On to step 4:
The number 30 fits into 54 1 times, leaving a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
The remainder is 24 after subtracting 30 from 54.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 30

Step 5:
247 divided by 30 is 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 518.0
Subtracting 240 from 247 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 30

Step 6:
30 can be fit into 79 2 times, resulting in a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 5182.0
If we subtract 60 from 79, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 30 fits into 190 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 5182.6
Subtracting 180 from 190 leaves us 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 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 5182.63
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.

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: 5182.633
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.

In conclusion, the division gives 5182.633 with a balance of 0.001.
