171715 ÷ 98 
The aim is to understand the frequency of 98 in 171715.

Moving on to step 1:
When dividing 1 by 98, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 98

On to step 2:
17 divided by 98 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 98

Moving on to step 3:
If we divide 171 by 98, we get 1 and a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 98 from 171, we get 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 98

On to step 4:
When dividing 737 by 98, we get 7 with a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 51 after subtracting 686 from 737.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 98

Advancing to step 5:
If we divide 511 by 98, we get 5 and a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 175.0
Subtract 490 from 511 to get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 98

Moving on to step 6:
215 divided by 98 is 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 1752.0
Subtract 196 from 215 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
98 goes into 190 1 times with a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 1752.1
If we take 98 away from 190, 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.

Step 8:
98 can be fit into 920 9 times, resulting in a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 1752.19
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.

Let's proceed to step 9:
If we divide 380 by 98, we get 3 and a remainder of 86.
The next digit of our result is 3. 
Result so far: 1752.193
The remainder is 86 after subtracting 294 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 10:
98 can be fit into 860 8 times, resulting in a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 1752.1938
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.

On to step 11:
98 goes into 760 7 times with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 1752.19387
Deduct 686 from 760 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 12:
When dividing 740 by 98, we get 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 1752.193877
Deduct 686 from 740 and we're left with 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 outcome is 1752.193877, with a leftover of 5.4e-06.
