540539 divided by 30 
The aim is to understand the frequency of 30 in 540539.

Let's proceed to step 1:
30 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 30

Moving on to step 2:
30 can be fit into 54 1 times, resulting in a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 30 from 54 to get 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 30

Advancing to step 3:
30 goes into 240 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 240 away from 240, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 30

Let's proceed to step 4:
The number 30 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 180.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 30

Advancing to step 5:
30 can be fit into 53 1 times, resulting in a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1801.0
The remainder is 23 after subtracting 30 from 53.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 30

Moving on to step 6:
239 divided by 30 is 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 18017.0
If we take 210 away from 239, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
When dividing 290 by 30, we get 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 18017.9
If we take 270 away from 290, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 18017.96
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
30 goes into 200 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 18017.966
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 18017.966, and the remainder is 0.002.
