Let's divide 98844 by 21
The aim is to understand the frequency of 21 in 98844.

Step 1:
21 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 21

On to step 2:
When dividing 98 by 21, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 84 from 98 to get 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 21

Let's proceed to step 3:
When dividing 148 by 21, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 147 away from 148, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 21

On to step 4:
14 divided by 21 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 470.0
If we take 0 away from 14, we end up with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 21

Moving on to step 5:
21 goes into 144 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 4706.0
If we take 126 away from 144, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 6:
180 divided by 21 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 4706.8
Deduct 168 from 180 and we're left 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 7:
When dividing 120 by 21, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 4706.85
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
21 goes into 150 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 4706.857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 4706.8571
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
If we divide 90 by 21, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 4706.85714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
21 can be fit into 60 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 4706.857142
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 4706.8571428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
120 divided by 21 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 4706.85714285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 4706.85714285 and a remainder of 1.5e-08.
