We look at the division of 93554618 by 543 
The aim is to understand the frequency of 543 in 93554618.

Advancing to step 1:
543 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 543

Moving on to step 2:
When dividing 93 by 543, we get 0 with a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 93 to get 93.
Grab the next digit (5) from the dividend, add it to 93, then carry on: 935 / 543

Moving on to step 3:
543 can be fit into 935 1 times, resulting in a remainder of 392.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 543 from 935 to get 392.
Bring next digit (5) of the dividend behind the 392 and repeat the process: 3925 / 543

On to step 4:
543 goes into 3925 7 times with a remainder of 124.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 3801 from 3925, we get 124.
Include the next digit (4) from the dividend after 124, then repeat: 1244 / 543

Step 5:
If we divide 1244 by 543, we get 2 and a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Deduct 1086 from 1244 and we're left with 158.
Bring next digit (6) of the dividend behind the 158 and repeat the process: 1586 / 543

On to step 6:
543 can be fit into 1586 2 times, resulting in a remainder of 500.
Record the quotient 2 as the next digit in the result. 
Result so far: 1722.0
If we take 1086 away from 1586, we end up with 500.
Fetch the next digit (1) from the dividend, attach it to 500 and continue: 5001 / 543

Let's proceed to step 7:
543 can be fit into 5001 9 times, resulting in a remainder of 114.
The number 9 becomes the next digit in our result. 
Result so far: 17229.0
Subtracting 4887 from 5001 leaves us with 114.
Grab the next digit (8) from the dividend, add it to 114, then carry on: 1148 / 543

Let's proceed to step 8:
543 can be fit into 1148 2 times, resulting in a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 172292.0
If we take 1086 away from 1148, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
543 goes into 620 1 times with a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 172292.1
The remainder is 77 after subtracting 543 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 10:
770 divided by 543 is 1 with a remainder of 227.
Record the quotient 1 as the next digit in the result. 
Result so far: 172292.11
Subtract 543 from 770 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

After the division, we end up with 172292.11 and a remainder of 0.227.
