Let's divide 25989848 by 30
The aim is to understand the frequency of 30 in 25989848.

On to step 1:
If we divide 2 by 30, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 30

On to step 2:
When dividing 25 by 30, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 30

Let's proceed to step 3:
259 divided by 30 is 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 240 from 259, we get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 30

Advancing to step 4:
30 goes into 198 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 180 from 198, we get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 30

Going ahead to step 5:
If we divide 189 by 30, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
If we take 180 away from 189, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 30

Going ahead to step 6:
If we divide 98 by 30, we get 3 and a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 8663.0
Subtract 90 from 98 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 30

On to step 7:
30 can be fit into 84 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 86632.0
The remainder is 24 after subtracting 60 from 84.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 30

Moving on to step 8:
The number 30 fits into 248 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 866328.0
If we subtract 240 from 248, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
If we divide 80 by 30, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 866328.2
Subtracting 60 from 80 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 10:
When dividing 200 by 30, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 866328.26
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.

Moving on to step 11:
If we divide 200 by 30, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 866328.266
If we take 180 away from 200, we end up 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.

In conclusion, the division gives 866328.266 with a balance of 0.002.
