171698 ÷ 98 
The aim is to understand the frequency of 98 in 171698.

Advancing to step 1:
If we divide 1 by 98, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 98

Moving on to step 2:
17 divided by 98 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 98

On to step 3:
98 goes into 171 1 times with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 73 after subtracting 98 from 171.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 98

On to step 4:
736 divided by 98 is 7 with a remainder of 50.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 686 from 736 leaves us with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 98

Advancing to step 5:
98 can be fit into 509 5 times, resulting in a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 175.0
The remainder is 19 after subtracting 490 from 509.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 98

On to step 6:
When dividing 198 by 98, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 1752.0
Subtract 196 from 198 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 98 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1752.0
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.

Moving on to step 8:
98 can be fit into 200 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1752.02
Deduct 196 from 200 and we're left 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: 1752.02
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.

Let's proceed to step 10:
When dividing 400 by 98, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 1752.0204
The remainder is 8 after subtracting 392 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 98, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 1752.0204
If we subtract 0 from 80, we 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.

Let's proceed to step 12:
The number 98 fits into 800 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 1752.020408
If we subtract 784 from 800, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
160 divided by 98 is 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 1752.0204081
Subtracting 98 from 160 leaves us 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.

On to step 14:
98 can be fit into 620 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1752.02040816
The remainder is 32 after subtracting 588 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 1752.02040816, with a leftover of 3.2e-08.
