1281 ÷ 30 
The aim is to understand the frequency of 30 in 1281.

Going ahead to step 1:
1 divided by 30 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 30

Step 2:
30 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 30

On to step 3:
The number 30 fits into 128 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 8 after subtracting 120 from 128.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 30

Let's proceed to step 4:
81 divided by 30 is 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 21 after subtracting 60 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 5:
The number 30 fits into 210 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 42.7
If we subtract 210 from 210, we get 0.
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 6:
If we divide 0 by 30, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42.7
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.

Step 7:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 42.7 with a remaining 0.0.
