We divide 539353 by 30
The aim is to understand the frequency of 30 in 539353.

Let's proceed to step 1:
5 divided by 30 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 30

Moving on to step 2:
The number 30 fits into 53 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 53 and we're left with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 30

Step 3:
The number 30 fits into 239 7 times, leaving a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 210 away from 239, we end up with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 30

Advancing to step 4:
293 divided by 30 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 179.0
If we subtract 270 from 293, we get 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 30

Let's proceed to step 5:
When dividing 235 by 30, we get 7 with a remainder of 25.
The next digit of our result is 7. 
Result so far: 1797.0
If we take 210 away from 235, we end up with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 30

Advancing to step 6:
253 divided by 30 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 17978.0
The remainder is 13 after subtracting 240 from 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
30 can be fit into 130 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 17978.4
Deduct 120 from 130 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 8:
30 goes into 100 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 17978.43
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.

Step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 17978.433
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.

The final outcome is 17978.433, with a leftover of 0.001.
