We're dividing 81504175 by 539 
The aim is to understand the frequency of 539 in 81504175.

Advancing to step 1:
539 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 539

Advancing to step 2:
The number 539 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 539

Going ahead to step 3:
When dividing 815 by 539, we get 1 with a remainder of 276.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 539 from 815, we get 276.
Grab the next digit (0) from the dividend, add it to 276, then carry on: 2760 / 539

Moving on to step 4:
The number 539 fits into 2760 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 2695 from 2760 leaves us with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 539

Step 5:
When dividing 654 by 539, we get 1 with a remainder of 115.
The next digit of our result is 1. 
Result so far: 151.0
Deduct 539 from 654 and we're left with 115.
Grab the next digit (1) from the dividend, add it to 115, then carry on: 1151 / 539

Let's proceed to step 6:
539 can be fit into 1151 2 times, resulting in a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 1512.0
If we take 1078 away from 1151, we end up with 73.
Grab the next digit (7) from the dividend, add it to 73, then carry on: 737 / 539

Advancing to step 7:
539 can be fit into 737 1 times, resulting in a remainder of 198.
Write down 1 as next digit of the result. 
Result so far: 15121.0
If we subtract 539 from 737, we get 198.
Append the next digit (5) from the dividend to 198 and continue with: 1985 / 539

On to step 8:
539 goes into 1985 3 times with a remainder of 368.
Use 3 as the next digit of our solution. 
Result so far: 151213.0
If we take 1617 away from 1985, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 9:
When dividing 3680 by 539, we get 6 with a remainder of 446.
The number 6 becomes the next digit in our result. 
Result so far: 151213.6
The remainder is 446 after subtracting 3234 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Advancing to step 10:
4460 divided by 539 is 8 with a remainder of 148.
Record the quotient 8 as the next digit in the result. 
Result so far: 151213.68
Deduct 4312 from 4460 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 11:
If we divide 1480 by 539, we get 2 and a remainder of 402.
Record the quotient 2 as the next digit in the result. 
Result so far: 151213.682
Deduct 1078 from 1480 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 12:
539 goes into 4020 7 times with a remainder of 247.
Use 7 as the next digit of our solution. 
Result so far: 151213.6827
If we subtract 3773 from 4020, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 13:
2470 divided by 539 is 4 with a remainder of 314.
Write down 4 as next digit of the result. 
Result so far: 151213.68274
Subtract 2156 from 2470 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 14:
3140 divided by 539 is 5 with a remainder of 445.
Write down 5 as next digit of the result. 
Result so far: 151213.682745
If we take 2695 away from 3140, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 15:
The number 539 fits into 4450 8 times, leaving a remainder of 138.
The number 8 becomes the next digit in our result. 
Result so far: 151213.6827458
If we subtract 4312 from 4450, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 16:
If we divide 1380 by 539, we get 2 and a remainder of 302.
Record the quotient 2 as the next digit in the result. 
Result so far: 151213.68274582
If we take 1078 away from 1380, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

The quotient of the division is 151213.68274582, and the remainder is 3.02e-07.
