Let's divide 68445660 by 543
The aim is to understand the frequency of 543 in 68445660.

On to step 1:
543 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 543

Step 2:
The number 543 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 543

On to step 3:
If we divide 684 by 543, we get 1 and a remainder of 141.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 543 from 684 and we're left with 141.
Bring next digit (4) of the dividend behind the 141 and repeat the process: 1414 / 543

Going ahead to step 4:
543 goes into 1414 2 times with a remainder of 328.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1086 from 1414, we get 328.
Append the next digit (5) from the dividend to 328 and continue with: 3285 / 543

Going ahead to step 5:
3285 divided by 543 is 6 with a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
The remainder is 27 after subtracting 3258 from 3285.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 543

Advancing to step 6:
When dividing 276 by 543, we get 0 with a remainder of 276.
Put 0 as the next digit of the answer. 
Result so far: 1260.0
If we take 0 away from 276, we end up with 276.
Include the next digit (6) from the dividend after 276, then repeat: 2766 / 543

Advancing to step 7:
2766 divided by 543 is 5 with a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 12605.0
Subtract 2715 from 2766 to get 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 543

Let's proceed to step 8:
The number 543 fits into 510 0 times, leaving a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 126050.0
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 9:
5100 divided by 543 is 9 with a remainder of 213.
The number 9 becomes the next digit in our result. 
Result so far: 126050.9
The remainder is 213 after subtracting 4887 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 10:
543 goes into 2130 3 times with a remainder of 501.
The number 3 becomes the next digit in our result. 
Result so far: 126050.93
Subtract 1629 from 2130 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

On to step 11:
The number 543 fits into 5010 9 times, leaving a remainder of 123.
The number 9 becomes the next digit in our result. 
Result so far: 126050.939
Subtracting 4887 from 5010 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 12:
543 can be fit into 1230 2 times, resulting in a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 126050.9392
Subtract 1086 from 1230 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 13:
When dividing 1440 by 543, we get 2 with a remainder of 354.
Use 2 as the next digit of our solution. 
Result so far: 126050.93922
The remainder is 354 after subtracting 1086 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Our division results in 126050.93922 with a remaining 0.000354.
