274001 divided by 21 
The aim is to understand the frequency of 21 in 274001.

Let's proceed to step 1:
21 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 21

Let's proceed to step 2:
The number 21 fits into 27 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 21 from 27 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 21

Let's proceed to step 3:
21 goes into 64 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 63 from 64 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 21

Advancing to step 4:
21 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 130.0
Deduct 0 from 10 and we're left with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 21

Going ahead to step 5:
21 can be fit into 100 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1304.0
Deduct 84 from 100 and we're left with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 21

Advancing to step 6:
The number 21 fits into 161 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 13047.0
Deduct 147 from 161 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 21 fits into 140 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 13047.6
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
When dividing 140 by 21, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 13047.66
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 13047.66 with a balance of 0.014.
