172148 divided by 98 
The aim is to understand the frequency of 98 in 172148.

Advancing to step 1:
When dividing 1 by 98, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 98

Let's proceed to step 2:
If we divide 17 by 98, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 98

Step 3:
98 can be fit into 172 1 times, resulting in a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 98 away from 172, we end up with 74.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 98

Advancing to step 4:
741 divided by 98 is 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 686 away from 741, we end up with 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 98

On to step 5:
When dividing 554 by 98, we get 5 with a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 175.0
Deduct 490 from 554 and we're left with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 98

Going ahead to step 6:
If we divide 648 by 98, we get 6 and a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 1756.0
If we take 588 away from 648, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
If we divide 600 by 98, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 1756.6
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 98 fits into 120 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1756.61
Deduct 98 from 120 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
If we divide 220 by 98, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 1756.612
If we take 196 away from 220, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
When dividing 240 by 98, we get 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 1756.6122
Subtracting 196 from 240 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 1756.6122, with a leftover of 0.00044.
