We look at the division of 863528 by 98 
The aim is to understand the frequency of 98 in 863528.

Step 1:
8 divided by 98 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 98

Advancing to step 2:
If we divide 86 by 98, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 98

Advancing to step 3:
The number 98 fits into 863 8 times, leaving a remainder of 79.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 784 away from 863, we end up with 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 98

Step 4:
98 goes into 795 8 times with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we take 784 away from 795, we end up with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 98

Moving on to step 5:
112 divided by 98 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 881.0
The remainder is 14 after subtracting 98 from 112.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 98

On to step 6:
If we divide 148 by 98, we get 1 and a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 8811.0
The remainder is 50 after subtracting 98 from 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
When dividing 500 by 98, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 8811.5
Subtracting 490 from 500 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.

Let's proceed to step 8:
98 goes into 100 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 8811.51
Subtract 98 from 100 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
The number 98 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8811.51
Subtracting 0 from 20 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.

On to step 10:
98 goes into 200 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 8811.5102
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
40 divided by 98 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8811.5102
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
98 can be fit into 400 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 8811.510204
Subtracting 392 from 400 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
98 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 8811.510204
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
The number 98 fits into 800 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 8811.51020408
If we subtract 784 from 800, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 8811.51020408, with a leftover of 1.6e-08.
