We look at the division of 872545 by 98 
The aim is to understand the frequency of 98 in 872545.

Going ahead to step 1:
If we divide 8 by 98, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 98

Moving on to step 2:
98 can be fit into 87 0 times, resulting in a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Bring next digit (2) of the dividend behind the 87 and repeat the process: 872 / 98

Going ahead to step 3:
When dividing 872 by 98, we get 8 with a remainder of 88.
The next digit of our result is 8. 
Result so far: 8.0
If we take 784 away from 872, we end up with 88.
Bring next digit (5) of the dividend behind the 88 and repeat the process: 885 / 98

Advancing to step 4:
When dividing 885 by 98, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
The remainder is 3 after subtracting 882 from 885.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 98

Step 5:
When dividing 34 by 98, we get 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 890.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 98

Advancing to step 6:
98 goes into 345 3 times with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 8903.0
Subtracting 294 from 345 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
98 can be fit into 510 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 8903.5
The remainder is 20 after subtracting 490 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 98 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 8903.52
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 98, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8903.52
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
98 can be fit into 400 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 8903.5204
If we take 392 away from 400, we end up 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.

Moving on to step 11:
98 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 8903.5204
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.

Step 12:
When dividing 800 by 98, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 8903.520408
If we take 784 away from 800, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
When dividing 160 by 98, we get 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 8903.5204081
If we take 98 away from 160, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 14:
620 divided by 98 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 8903.52040816
Subtract 588 from 620 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 8903.52040816 and a remainder of 3.2e-08.
