891959 ÷ 98 
The aim is to understand the frequency of 98 in 891959.

Moving on to step 1:
If we divide 8 by 98, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 98

On to step 2:
98 can be fit into 89 0 times, resulting in a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 98

Let's proceed to step 3:
891 divided by 98 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 882 from 891 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 98

Going ahead to step 4:
When dividing 99 by 98, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtract 98 from 99 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 98

Let's proceed to step 5:
98 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 910.0
Subtract 0 from 15 to get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 98

Let's proceed to step 6:
98 can be fit into 159 1 times, resulting in a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 9101.0
Subtracting 98 from 159 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
The number 98 fits into 610 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 9101.6
If we subtract 588 from 610, we get 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 8:
220 divided by 98 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 9101.62
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.

Moving on to step 9:
The number 98 fits into 240 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 9101.622
The remainder is 44 after subtracting 196 from 240.
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 9101.622, with a leftover of 0.0044.
