We divide 350281 by 30
The aim is to understand the frequency of 30 in 350281.

Moving on to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 30

Step 2:
If we divide 35 by 30, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 35 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 30

Advancing to step 3:
30 goes into 50 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 30 from 50, we get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 30

On to step 4:
202 divided by 30 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Deduct 180 from 202 and we're left with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 30

Let's proceed to step 5:
If we divide 228 by 30, we get 7 and a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 1167.0
If we subtract 210 from 228, we get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 30

On to step 6:
30 goes into 181 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 11676.0
Subtract 180 from 181 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 30 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 11676.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 11676.03
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.

Step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 11676.033
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 result is 11676.033 with a remainder of 0.001.
