We look at the division of 720109 by 98 
The aim is to understand the frequency of 98 in 720109.

On to step 1:
If we divide 7 by 98, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 98

Moving on to step 2:
When dividing 72 by 98, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 98

Let's proceed to step 3:
When dividing 720 by 98, we get 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 686 from 720, we get 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 98

On to step 4:
When dividing 341 by 98, we get 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtracting 294 from 341 leaves us with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 98

Going ahead to step 5:
The number 98 fits into 470 4 times, leaving a remainder of 78.
The next digit of our result is 4. 
Result so far: 734.0
If we subtract 392 from 470, we get 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 98

Moving on to step 6:
When dividing 789 by 98, we get 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 7348.0
Subtract 784 from 789 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 98 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7348.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
98 goes into 500 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 7348.05
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.

On to step 9:
If we divide 100 by 98, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 7348.051
Deduct 98 from 100 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
If we divide 20 by 98, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7348.051
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.

Going ahead to step 11:
98 goes into 200 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 7348.05102
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.

Let's proceed to step 12:
If we divide 40 by 98, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7348.05102
If we subtract 0 from 40, we 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.

Advancing to step 13:
400 divided by 98 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 7348.0510204
Subtract 392 from 400 to 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 14:
If we divide 80 by 98, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 7348.0510204
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 7348.0510204, and the remainder is 8e-08.
