We're dividing 583155 by 30 
The aim is to understand the frequency of 30 in 583155.

Step 1:
30 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 30

Advancing to step 2:
The number 30 fits into 58 1 times, leaving a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 30 from 58 leaves us with 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 30

On to step 3:
The number 30 fits into 283 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 13 after subtracting 270 from 283.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 30

Moving on to step 4:
30 can be fit into 131 4 times, resulting in a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
Subtract 120 from 131 to get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 30

Going ahead to step 5:
The number 30 fits into 115 3 times, leaving a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 1943.0
If we take 90 away from 115, we end up with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 30

Let's proceed to step 6:
30 goes into 255 8 times with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 19438.0
Subtract 240 from 255 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
150 divided by 30 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 19438.5
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19438.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
30 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19438.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 19438.5, with a leftover of 0.0.
