We divide 276833 by 21
The aim is to understand the frequency of 21 in 276833.

On to step 1:
21 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 21

Let's proceed to step 2:
When dividing 27 by 21, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 21 from 27 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 21

On to step 3:
21 can be fit into 66 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 3 after subtracting 63 from 66.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 21

Advancing to step 4:
21 goes into 38 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Deduct 21 from 38 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 21

Step 5:
The number 21 fits into 173 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 1318.0
Subtracting 168 from 173 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 21

Let's proceed to step 6:
53 divided by 21 is 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 13182.0
If we take 42 away from 53, 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.

Let's proceed to step 7:
21 goes into 110 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 13182.5
If we take 105 away from 110, we end up 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.

Moving on to step 8:
50 divided by 21 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 13182.52
If we take 42 away from 50, we end up 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.

Moving on to step 9:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 13182.523
If we take 63 away from 80, we end up 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.

Let's proceed to step 10:
170 divided by 21 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 13182.5238
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.

Step 11:
If we divide 20 by 21, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 13182.5238
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.

Let's proceed to step 12:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 13182.523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 13182.5238095
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.

Going ahead to step 14:
50 divided by 21 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 13182.52380952
If we take 42 away from 50, we end up 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.

In conclusion, the division gives 13182.52380952 with a balance of 8e-09.
