658354 divided by 30 
The aim is to understand the frequency of 30 in 658354.

On to step 1:
30 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 30

Let's proceed to step 2:
When dividing 65 by 30, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 60 from 65 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 30

Let's proceed to step 3:
30 goes into 58 1 times with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 30 away from 58, we end up with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 30

Going ahead to step 4:
30 can be fit into 283 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
The remainder is 13 after subtracting 270 from 283.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 30

On to step 5:
135 divided by 30 is 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 2194.0
If we subtract 120 from 135, we get 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 30

Advancing to step 6:
30 can be fit into 154 5 times, resulting in a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 21945.0
Subtracting 150 from 154 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
30 goes into 40 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 21945.1
If we take 30 away from 40, we end up 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.

Step 8:
30 goes into 100 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 21945.13
If we subtract 90 from 100, we 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 9:
100 divided by 30 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 21945.133
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.

The final result is 21945.133 with a remainder of 0.001.
