848946 ÷ 30 
The aim is to understand the frequency of 30 in 848946.

Step 1:
30 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 30

Going ahead to step 2:
When dividing 84 by 30, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 60 from 84 and we're left with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 30

Step 3:
30 goes into 248 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 240 from 248 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 30

On to step 4:
89 divided by 30 is 2 with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 282.0
Subtracting 60 from 89 leaves us with 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 30

On to step 5:
30 goes into 294 9 times with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 2829.0
If we subtract 270 from 294, we get 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 30

Let's proceed to step 6:
If we divide 246 by 30, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 28298.0
If we subtract 240 from 246, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
30 goes into 60 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 28298.2
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28298.2
Deduct 0 from 0 and we're left 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.

On to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28298.2
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.

After the division, we end up with 28298.2 and a remainder of 0.0.
