We're dividing 98812581 by 260 
The aim is to understand the frequency of 260 in 98812581.

Going ahead to step 1:
If we divide 9 by 260, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 260

On to step 2:
If we divide 98 by 260, we get 0 and a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Bring next digit (8) of the dividend behind the 98 and repeat the process: 988 / 260

Let's proceed to step 3:
988 divided by 260 is 3 with a remainder of 208.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 780 from 988 and we're left with 208.
Include the next digit (1) from the dividend after 208, then repeat: 2081 / 260

Moving on to step 4:
When dividing 2081 by 260, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 2080 from 2081 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 260

Going ahead to step 5:
260 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 380.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 260

Let's proceed to step 6:
125 divided by 260 is 0 with a remainder of 125.
Write down 0 as next digit of the result. 
Result so far: 3800.0
If we subtract 0 from 125, we get 125.
Grab the next digit (8) from the dividend, add it to 125, then carry on: 1258 / 260

Going ahead to step 7:
260 goes into 1258 4 times with a remainder of 218.
Write down 4 as next digit of the result. 
Result so far: 38004.0
Subtract 1040 from 1258 to get 218.
Append the next digit (1) from the dividend to 218 and continue with: 2181 / 260

On to step 8:
2181 divided by 260 is 8 with a remainder of 101.
Put 8 as the next digit of the answer. 
Result so far: 380048.0
The remainder is 101 after subtracting 2080 from 2181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
260 can be fit into 1010 3 times, resulting in a remainder of 230.
Put 3 as the next digit of the answer. 
Result so far: 380048.3
Deduct 780 from 1010 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
When dividing 2300 by 260, we get 8 with a remainder of 220.
Use 8 as the next digit of our solution. 
Result so far: 380048.38
If we take 2080 away from 2300, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
The number 260 fits into 2200 8 times, leaving a remainder of 120.
The next digit of our result is 8. 
Result so far: 380048.388
If we take 2080 away from 2200, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 380048.388 with a balance of 0.012.
