Let's divide 958250 by 30
The aim is to understand the frequency of 30 in 958250.

Advancing to step 1:
30 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 30

Going ahead to step 2:
95 divided by 30 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 90 from 95 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 30

On to step 3:
If we divide 58 by 30, we get 1 and a remainder of 28.
The next digit of our result is 1. 
Result so far: 31.0
If we take 30 away from 58, we end up with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 30

Advancing to step 4:
30 can be fit into 282 9 times, resulting in a remainder of 12.
The next digit of our result is 9. 
Result so far: 319.0
Subtract 270 from 282 to get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 30

Step 5:
30 goes into 125 4 times with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 3194.0
The remainder is 5 after subtracting 120 from 125.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 30

On to step 6:
50 divided by 30 is 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 31941.0
The remainder is 20 after subtracting 30 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 31941.6
If we take 180 away from 200, we end up 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:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 31941.66
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 31941.66 with a remaining 0.02.
