We divide 416267 by 21
The aim is to understand the frequency of 21 in 416267.

Let's proceed to step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 21

On to step 2:
21 can be fit into 41 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 20 after subtracting 21 from 41.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 21

On to step 3:
206 divided by 21 is 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 189 from 206, we get 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 21

Going ahead to step 4:
When dividing 172 by 21, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
The remainder is 4 after subtracting 168 from 172.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 21

Advancing to step 5:
If we divide 46 by 21, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 1982.0
Subtract 42 from 46 to get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 21

Moving on to step 6:
21 can be fit into 47 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 19822.0
The remainder is 5 after subtracting 42 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
21 goes into 50 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 19822.2
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.

On to step 8:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 19822.23
Subtract 63 from 80 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.

On to step 9:
21 goes into 170 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 19822.238
The remainder is 2 after subtracting 168 from 170.
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 10:
If we divide 20 by 21, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 19822.238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 21 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 19822.23809
Deduct 189 from 200 and we're left 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.

Let's proceed to step 12:
When dividing 110 by 21, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 19822.238095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
If we divide 50 by 21, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 19822.2380952
Subtracting 42 from 50 leaves us 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.

On to step 14:
If we divide 80 by 21, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 19822.23809523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 19822.23809523 with a balance of 1.7e-08.
