Let's divide 289481 by 30
The aim is to understand the frequency of 30 in 289481.

Step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 30

Let's proceed to step 2:
When dividing 28 by 30, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 30

Let's proceed to step 3:
289 divided by 30 is 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 270 from 289 leaves us with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 30

Let's proceed to step 4:
30 can be fit into 194 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Subtract 180 from 194 to get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 30

Step 5:
If we divide 148 by 30, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 964.0
Subtract 120 from 148 to get 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 30

Moving on to step 6:
30 goes into 281 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9649.0
The remainder is 11 after subtracting 270 from 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
If we divide 110 by 30, we get 3 and a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 9649.3
Deduct 90 from 110 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.

Let's proceed to step 8:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 9649.36
Subtracting 180 from 200 leaves us 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.

Let's proceed to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 9649.366
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.

Our division results in 9649.366 with a remaining 0.002.
