We're dividing 81733628 by 543 
The aim is to understand the frequency of 543 in 81733628.

Advancing to step 1:
543 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 543

Moving on to step 2:
81 divided by 543 is 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 543

Going ahead to step 3:
The number 543 fits into 817 1 times, leaving a remainder of 274.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 543 away from 817, we end up with 274.
Take the next digit (3) from the dividend and append it to 274, then repeat: 2743 / 543

Moving on to step 4:
The number 543 fits into 2743 5 times, leaving a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 2715 from 2743, we get 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 543

Let's proceed to step 5:
When dividing 283 by 543, we get 0 with a remainder of 283.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtract 0 from 283 to get 283.
Grab the next digit (6) from the dividend, add it to 283, then carry on: 2836 / 543

Let's proceed to step 6:
When dividing 2836 by 543, we get 5 with a remainder of 121.
Write down 5 as next digit of the result. 
Result so far: 1505.0
If we subtract 2715 from 2836, we get 121.
Take the next digit (2) from the dividend and append it to 121, then repeat: 1212 / 543

Let's proceed to step 7:
543 goes into 1212 2 times with a remainder of 126.
The number 2 becomes the next digit in our result. 
Result so far: 15052.0
If we take 1086 away from 1212, we end up with 126.
Bring next digit (8) of the dividend behind the 126 and repeat the process: 1268 / 543

Going ahead to step 8:
543 can be fit into 1268 2 times, resulting in a remainder of 182.
Write down 2 as next digit of the result. 
Result so far: 150522.0
If we take 1086 away from 1268, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 9:
The number 543 fits into 1820 3 times, leaving a remainder of 191.
The number 3 becomes the next digit in our result. 
Result so far: 150522.3
Subtracting 1629 from 1820 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 10:
The number 543 fits into 1910 3 times, leaving a remainder of 281.
The next digit of our result is 3. 
Result so far: 150522.33
Subtract 1629 from 1910 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

The quotient of the division is 150522.33, and the remainder is 0.281.
