Let's divide 192293 by 21
The aim is to understand the frequency of 21 in 192293.

Going ahead to step 1:
1 divided by 21 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 21

Going ahead to step 2:
When dividing 19 by 21, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 21

Moving on to step 3:
21 can be fit into 192 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 189 from 192 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 21

Step 4:
21 goes into 32 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we take 21 away from 32, we end up with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 21

Step 5:
119 divided by 21 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 915.0
If we take 105 away from 119, we end up with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 21

On to step 6:
If we divide 143 by 21, we get 6 and a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 9156.0
Subtract 126 from 143 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
170 divided by 21 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 9156.8
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 9156.8
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 9:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 9156.809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 9156.8095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 9156.80952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
21 can be fit into 80 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 9156.809523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 9156.8095238
If we subtract 168 from 170, we 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.

Let's proceed to step 14:
If we divide 20 by 21, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 9156.8095238
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.

Our division results in 9156.8095238 with a remaining 2e-08.
