We look at the division of 866260 by 98 
The aim is to understand the frequency of 98 in 866260.

Step 1:
98 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
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 98

Advancing to step 2:
If we divide 86 by 98, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 98

Going ahead to step 3:
If we divide 866 by 98, we get 8 and a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 784 away from 866, we end up with 82.
Append the next digit (2) from the dividend to 82 and continue with: 822 / 98

Step 4:
If we divide 822 by 98, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Deduct 784 from 822 and we're left with 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 98

Advancing to step 5:
If we divide 386 by 98, we get 3 and a remainder of 92.
The next digit of our result is 3. 
Result so far: 883.0
If we take 294 away from 386, we end up with 92.
Take the next digit (0) from the dividend and append it to 92, then repeat: 920 / 98

Let's proceed to step 6:
98 can be fit into 920 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 8839.0
Subtracting 882 from 920 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
98 goes into 380 3 times with a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 8839.3
Subtracting 294 from 380 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 8:
If we divide 860 by 98, we get 8 and a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 8839.38
Subtract 784 from 860 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
760 divided by 98 is 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 8839.387
The remainder is 74 after subtracting 686 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
The number 98 fits into 740 7 times, leaving a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 8839.3877
If we subtract 686 from 740, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 8839.3877 with a remaining 0.00054.
