654490 divided by 30 
The aim is to understand the frequency of 30 in 654490.

Going ahead to step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 30

Going ahead to step 2:
30 can be fit into 65 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 60 from 65 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 30

Moving on to step 3:
30 goes into 54 1 times with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 24 after subtracting 30 from 54.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 30

Step 4:
30 can be fit into 244 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
Subtract 240 from 244 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 30

Step 5:
49 divided by 30 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 2181.0
Subtract 30 from 49 to get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 30

Step 6:
190 divided by 30 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 21816.0
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 30, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 21816.3
Subtract 90 from 100 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.

Moving on to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 21816.33
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.

The final outcome is 21816.33, with a leftover of 0.01.
