We look at the division of 597961 by 98 
The aim is to understand the frequency of 98 in 597961.

Step 1:
The number 98 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 98

Moving on to step 2:
98 can be fit into 59 0 times, resulting in a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 98

Advancing to step 3:
If we divide 597 by 98, we get 6 and a remainder of 9.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 588 from 597 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 98

Advancing to step 4:
98 can be fit into 99 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtract 98 from 99 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 98

Going ahead to step 5:
The number 98 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 610.0
If we take 0 away from 16, we end up with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 98

Step 6:
When dividing 161 by 98, we get 1 with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 6101.0
Deduct 98 from 161 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
When dividing 630 by 98, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 6101.6
If we subtract 588 from 630, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
The number 98 fits into 420 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 6101.64
If we subtract 392 from 420, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
The number 98 fits into 280 2 times, leaving a remainder of 84.
The next digit of our result is 2. 
Result so far: 6101.642
The remainder is 84 after subtracting 196 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
If we divide 840 by 98, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 6101.6428
If we take 784 away from 840, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
If we divide 560 by 98, we get 5 and a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 6101.64285
Deduct 490 from 560 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
98 can be fit into 700 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 6101.642857
Subtracting 686 from 700 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
98 goes into 140 1 times with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 6101.6428571
Deduct 98 from 140 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
When dividing 420 by 98, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 6101.64285714
If we subtract 392 from 420, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 6101.64285714 with a remaining 2.8e-08.
