We're dividing 43090243 by 549 
The aim is to understand the frequency of 549 in 43090243.

Step 1:
549 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 549

Going ahead to step 2:
549 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 549

Let's proceed to step 3:
If we divide 430 by 549, we get 0 and a remainder of 430.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 430 and we're left with 430.
Fetch the next digit (9) from the dividend, attach it to 430 and continue: 4309 / 549

Going ahead to step 4:
The number 549 fits into 4309 7 times, leaving a remainder of 466.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 3843 away from 4309, we end up with 466.
Fetch the next digit (0) from the dividend, attach it to 466 and continue: 4660 / 549

Moving on to step 5:
If we divide 4660 by 549, we get 8 and a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 4392 from 4660 and we're left with 268.
Grab the next digit (2) from the dividend, add it to 268, then carry on: 2682 / 549

Let's proceed to step 6:
549 can be fit into 2682 4 times, resulting in a remainder of 486.
The next digit of our result is 4. 
Result so far: 784.0
The remainder is 486 after subtracting 2196 from 2682.
Include the next digit (4) from the dividend after 486, then repeat: 4864 / 549

Going ahead to step 7:
When dividing 4864 by 549, we get 8 with a remainder of 472.
The number 8 becomes the next digit in our result. 
Result so far: 7848.0
The remainder is 472 after subtracting 4392 from 4864.
Take the next digit (3) from the dividend and append it to 472, then repeat: 4723 / 549

Going ahead to step 8:
549 can be fit into 4723 8 times, resulting in a remainder of 331.
Write down 8 as next digit of the result. 
Result so far: 78488.0
Deduct 4392 from 4723 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 9:
If we divide 3310 by 549, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 78488.6
Subtracting 3294 from 3310 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 549, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 78488.6
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
If we divide 1600 by 549, we get 2 and a remainder of 502.
Put 2 as the next digit of the answer. 
Result so far: 78488.602
If we take 1098 away from 1600, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 12:
549 can be fit into 5020 9 times, resulting in a remainder of 79.
The next digit of our result is 9. 
Result so far: 78488.6029
The remainder is 79 after subtracting 4941 from 5020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 13:
The number 549 fits into 790 1 times, leaving a remainder of 241.
The number 1 becomes the next digit in our result. 
Result so far: 78488.60291
Subtracting 549 from 790 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Advancing to step 14:
The number 549 fits into 2410 4 times, leaving a remainder of 214.
Put 4 as the next digit of the answer. 
Result so far: 78488.602914
The remainder is 214 after subtracting 2196 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 15:
549 goes into 2140 3 times with a remainder of 493.
The next digit of our result is 3. 
Result so far: 78488.6029143
If we take 1647 away from 2140, we end up with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

On to step 16:
4930 divided by 549 is 8 with a remainder of 538.
Write down 8 as next digit of the result. 
Result so far: 78488.60291438
The remainder is 538 after subtracting 4392 from 4930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Our division results in 78488.60291438 with a remaining 5.38e-07.
