We look at the division of 49502109 by 543 
The aim is to understand the frequency of 543 in 49502109.

Step 1:
If we divide 4 by 543, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 543

Step 2:
49 divided by 543 is 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 543

Let's proceed to step 3:
If we divide 495 by 543, we get 0 and a remainder of 495.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 495 after subtracting 0 from 495.
Append the next digit (0) from the dividend to 495 and continue with: 4950 / 543

Moving on to step 4:
543 goes into 4950 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 4887 from 4950 and we're left with 63.
Bring next digit (2) of the dividend behind the 63 and repeat the process: 632 / 543

Advancing to step 5:
The number 543 fits into 632 1 times, leaving a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtract 543 from 632 to get 89.
Grab the next digit (1) from the dividend, add it to 89, then carry on: 891 / 543

Going ahead to step 6:
When dividing 891 by 543, we get 1 with a remainder of 348.
The number 1 becomes the next digit in our result. 
Result so far: 911.0
Subtract 543 from 891 to get 348.
Bring next digit (0) of the dividend behind the 348 and repeat the process: 3480 / 543

On to step 7:
If we divide 3480 by 543, we get 6 and a remainder of 222.
Write down 6 as next digit of the result. 
Result so far: 9116.0
If we take 3258 away from 3480, we end up with 222.
Fetch the next digit (9) from the dividend, attach it to 222 and continue: 2229 / 543

Advancing to step 8:
When dividing 2229 by 543, we get 4 with a remainder of 57.
Use 4 as the next digit of our solution. 
Result so far: 91164.0
If we take 2172 away from 2229, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
543 can be fit into 570 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 91164.1
Subtracting 543 from 570 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
If we divide 270 by 543, we get 0 and a remainder of 270.
The next digit of our result is 0. 
Result so far: 91164.1
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
When dividing 2700 by 543, we get 4 with a remainder of 528.
Record the quotient 4 as the next digit in the result. 
Result so far: 91164.104
Subtracting 2172 from 2700 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 12:
543 goes into 5280 9 times with a remainder of 393.
Write down 9 as next digit of the result. 
Result so far: 91164.1049
Deduct 4887 from 5280 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Step 13:
When dividing 3930 by 543, we get 7 with a remainder of 129.
The next digit of our result is 7. 
Result so far: 91164.10497
Subtracting 3801 from 3930 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 14:
The number 543 fits into 1290 2 times, leaving a remainder of 204.
The next digit of our result is 2. 
Result so far: 91164.104972
If we subtract 1086 from 1290, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 15:
543 can be fit into 2040 3 times, resulting in a remainder of 411.
Write down 3 as next digit of the result. 
Result so far: 91164.1049723
Subtracting 1629 from 2040 leaves us with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Step 16:
543 can be fit into 4110 7 times, resulting in a remainder of 309.
Write down 7 as next digit of the result. 
Result so far: 91164.10497237
Subtracting 3801 from 4110 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Our division results in 91164.10497237 with a remaining 3.09e-07.
