848500 ÷ 30 
The aim is to understand the frequency of 30 in 848500.

Let's proceed to step 1:
30 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 30

Let's proceed to step 2:
If we divide 84 by 30, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 60 away from 84, we end up with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 30

Let's proceed to step 3:
When dividing 248 by 30, we get 8 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.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 30

Let's proceed to step 4:
30 goes into 85 2 times with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 282.0
Subtract 60 from 85 to get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 30

Advancing to step 5:
30 goes into 250 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 2828.0
The remainder is 10 after subtracting 240 from 250.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 30

On to step 6:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 28283.0
Deduct 90 from 100 and we're left with 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 7:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 28283.3
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 28283.33
Subtracting 90 from 100 leaves us with 10.
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 outcome is 28283.33, with a leftover of 0.01.
