518101 ÷ 98 
The aim is to understand the frequency of 98 in 518101.

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
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 98

Step 2:
If we divide 51 by 98, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 98

Step 3:
98 goes into 518 5 times with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 490 from 518 leaves us with 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 98

Let's proceed to step 4:
The number 98 fits into 281 2 times, leaving a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Deduct 196 from 281 and we're left with 85.
Fetch the next digit (0) from the dividend, attach it to 85 and continue: 850 / 98

Step 5:
If we divide 850 by 98, we get 8 and a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 528.0
If we take 784 away from 850, we end up with 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 98

Step 6:
The number 98 fits into 661 6 times, leaving a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 5286.0
If we take 588 away from 661, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
If we divide 730 by 98, we get 7 and a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 5286.7
Subtracting 686 from 730 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.

Going ahead to step 8:
98 can be fit into 440 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 5286.74
If we subtract 392 from 440, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
98 can be fit into 480 4 times, resulting in a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 5286.744
If we subtract 392 from 480, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final outcome is 5286.744, with a leftover of 0.0088.
