Let's divide 16482 by 21
The aim is to understand the frequency of 21 in 16482.

Let's proceed to step 1:
1 divided by 21 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 21

Step 2:
If we divide 16 by 21, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 21

Moving on to step 3:
The number 21 fits into 164 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 147 from 164 and we're left with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 21

Moving on to step 4:
When dividing 178 by 21, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Deduct 168 from 178 and we're left with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 21

On to step 5:
When dividing 102 by 21, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 784.0
If we subtract 84 from 102, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 6:
If we divide 180 by 21, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 784.8
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.

Moving on to step 7:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 784.85
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.

Moving on to step 8:
When dividing 150 by 21, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 784.857
If we subtract 147 from 150, we get 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 goes into 30 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 784.8571
If we subtract 21 from 30, we 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.

Step 10:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 784.85714
Subtract 84 from 90 to get 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:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 784.857142
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.

Advancing to step 12:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 784.8571428
Subtract 168 from 180 to 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.

On to step 13:
When dividing 120 by 21, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 784.85714285
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.

In conclusion, the division gives 784.85714285 with a balance of 1.5e-08.
