We divide 21242468 by 549
The aim is to understand the frequency of 549 in 21242468.

Moving on to step 1:
When dividing 2 by 549, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 549

Step 2:
549 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 549

Going ahead to step 3:
The number 549 fits into 212 0 times, leaving a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Take the next digit (4) from the dividend and append it to 212, then repeat: 2124 / 549

Moving on to step 4:
2124 divided by 549 is 3 with a remainder of 477.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1647 from 2124 and we're left with 477.
Bring next digit (2) of the dividend behind the 477 and repeat the process: 4772 / 549

Let's proceed to step 5:
549 goes into 4772 8 times with a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtract 4392 from 4772 to get 380.
Take the next digit (4) from the dividend and append it to 380, then repeat: 3804 / 549

Going ahead to step 6:
549 goes into 3804 6 times with a remainder of 510.
The next digit of our result is 6. 
Result so far: 386.0
If we take 3294 away from 3804, we end up with 510.
Bring next digit (6) of the dividend behind the 510 and repeat the process: 5106 / 549

Step 7:
If we divide 5106 by 549, we get 9 and a remainder of 165.
Put 9 as the next digit of the answer. 
Result so far: 3869.0
If we subtract 4941 from 5106, we get 165.
Take the next digit (8) from the dividend and append it to 165, then repeat: 1658 / 549

Advancing to step 8:
If we divide 1658 by 549, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 38693.0
Subtract 1647 from 1658 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
110 divided by 549 is 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 38693.0
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
549 goes into 1100 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 38693.02
If we take 1098 away from 1100, 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.

On to step 11:
20 divided by 549 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 38693.02
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
549 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 38693.02
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 38693.02, with a leftover of 0.002.
