Let's divide 19279 by 21
The aim is to understand the frequency of 21 in 19279.

Moving on to step 1:
The number 21 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 21

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
If we take 0 away from 19, we end up with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 21

Going ahead to step 3:
21 goes into 192 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 189 from 192 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 21

Step 4:
If we divide 37 by 21, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 21 from 37 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 21

Let's proceed to step 5:
The number 21 fits into 169 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 918.0
If we take 168 away from 169, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
When dividing 10 by 21, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 918.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 918.04
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 918.047
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 918.0476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 21, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 918.04761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
When dividing 190 by 21, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 918.047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
When dividing 10 by 21, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 918.047619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 918.04761904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 918.04761904 with a balance of 1.6e-08.
