We look at the division of 577315 by 98 
The aim is to understand the frequency of 98 in 577315.

Step 1:
The number 98 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 98

Step 2:
If we divide 57 by 98, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Append the next digit (7) from the dividend to 57 and continue with: 577 / 98

Going ahead to step 3:
If we divide 577 by 98, we get 5 and a remainder of 87.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 490 from 577 to get 87.
Bring next digit (3) of the dividend behind the 87 and repeat the process: 873 / 98

Moving on to step 4:
98 can be fit into 873 8 times, resulting in a remainder of 89.
The next digit of our result is 8. 
Result so far: 58.0
If we subtract 784 from 873, we get 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 98

Moving on to step 5:
The number 98 fits into 891 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 589.0
Deduct 882 from 891 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 98

Advancing to step 6:
If we divide 95 by 98, we get 0 and a remainder of 95.
The number 0 becomes the next digit in our result. 
Result so far: 5890.0
Subtracting 0 from 95 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 7:
When dividing 950 by 98, we get 9 with a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 5890.9
Deduct 882 from 950 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
98 goes into 680 6 times with a remainder of 92.
The next digit of our result is 6. 
Result so far: 5890.96
If we take 588 away from 680, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 9:
98 goes into 920 9 times with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 5890.969
If we take 882 away from 920, we end up 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.

Moving on to step 10:
When dividing 380 by 98, we get 3 with a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 5890.9693
If we take 294 away from 380, we end up 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.

Going ahead to step 11:
98 can be fit into 860 8 times, resulting in a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 5890.96938
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.

Advancing to step 12:
When dividing 760 by 98, we get 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 5890.969387
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.

Step 13:
740 divided by 98 is 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 5890.9693877
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.

The final result is 5890.9693877 with a remainder of 5.4e-07.
