We look at the division of 72659866 by 543 
The aim is to understand the frequency of 543 in 72659866.

Moving on to step 1:
543 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 543

On to step 2:
If we divide 72 by 543, we get 0 and a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 543

Advancing to step 3:
The number 543 fits into 726 1 times, leaving a remainder of 183.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 543 from 726, we get 183.
Fetch the next digit (5) from the dividend, attach it to 183 and continue: 1835 / 543

Moving on to step 4:
The number 543 fits into 1835 3 times, leaving a remainder of 206.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1629 from 1835 and we're left with 206.
Append the next digit (9) from the dividend to 206 and continue with: 2069 / 543

Moving on to step 5:
When dividing 2069 by 543, we get 3 with a remainder of 440.
Put 3 as the next digit of the answer. 
Result so far: 133.0
Subtracting 1629 from 2069 leaves us with 440.
Append the next digit (8) from the dividend to 440 and continue with: 4408 / 543

Step 6:
When dividing 4408 by 543, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 1338.0
The remainder is 64 after subtracting 4344 from 4408.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 543

Advancing to step 7:
543 can be fit into 646 1 times, resulting in a remainder of 103.
Use 1 as the next digit of our solution. 
Result so far: 13381.0
If we take 543 away from 646, we end up with 103.
Bring next digit (6) of the dividend behind the 103 and repeat the process: 1036 / 543

On to step 8:
543 can be fit into 1036 1 times, resulting in a remainder of 493.
The number 1 becomes the next digit in our result. 
Result so far: 133811.0
If we take 543 away from 1036, 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.

Advancing to step 9:
The number 543 fits into 4930 9 times, leaving a remainder of 43.
The next digit of our result is 9. 
Result so far: 133811.9
Subtracting 4887 from 4930 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
The number 543 fits into 430 0 times, leaving a remainder of 430.
Put 0 as the next digit of the answer. 
Result so far: 133811.9
Deduct 0 from 430 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 11:
The number 543 fits into 4300 7 times, leaving a remainder of 499.
The next digit of our result is 7. 
Result so far: 133811.907
The remainder is 499 after subtracting 3801 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Moving on to step 12:
When dividing 4990 by 543, we get 9 with a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 133811.9079
The remainder is 103 after subtracting 4887 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 13:
When dividing 1030 by 543, we get 1 with a remainder of 487.
Use 1 as the next digit of our solution. 
Result so far: 133811.90791
If we take 543 away from 1030, we end up with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Advancing to step 14:
If we divide 4870 by 543, we get 8 and a remainder of 526.
Write down 8 as next digit of the result. 
Result so far: 133811.907918
If we take 4344 away from 4870, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 15:
543 goes into 5260 9 times with a remainder of 373.
The number 9 becomes the next digit in our result. 
Result so far: 133811.9079189
If we take 4887 away from 5260, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 16:
If we divide 3730 by 543, we get 6 and a remainder of 472.
The next digit of our result is 6. 
Result so far: 133811.90791896
Deduct 3258 from 3730 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

In conclusion, the division gives 133811.90791896 with a balance of 4.72e-07.
