We look at the division of 58259 by 30 
The aim is to understand the frequency of 30 in 58259.

Going ahead to step 1:
30 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 30

On to step 2:
When dividing 58 by 30, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 28 after subtracting 30 from 58.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 30

Advancing to step 3:
282 divided by 30 is 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 12 after subtracting 270 from 282.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 30

Advancing to step 4:
When dividing 125 by 30, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 194.0
The remainder is 5 after subtracting 120 from 125.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 30

On to step 5:
The number 30 fits into 59 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 1941.0
Deduct 30 from 59 and we're left 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.

Step 6:
290 divided by 30 is 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 1941.9
The remainder is 20 after subtracting 270 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
If we divide 200 by 30, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 1941.96
Deduct 180 from 200 and we're left 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.

Advancing to step 8:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 1941.966
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 1941.966 and a remainder of 0.002.
