We're dividing 89941073 by 539 
The aim is to understand the frequency of 539 in 89941073.

Going ahead to step 1:
8 divided by 539 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 539

Advancing to step 2:
539 goes into 89 0 times with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Bring next digit (9) of the dividend behind the 89 and repeat the process: 899 / 539

Advancing to step 3:
The number 539 fits into 899 1 times, leaving a remainder of 360.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 360 after subtracting 539 from 899.
Append the next digit (4) from the dividend to 360 and continue with: 3604 / 539

Step 4:
539 goes into 3604 6 times with a remainder of 370.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 3234 from 3604 leaves us with 370.
Fetch the next digit (1) from the dividend, attach it to 370 and continue: 3701 / 539

Going ahead to step 5:
539 goes into 3701 6 times with a remainder of 467.
Put 6 as the next digit of the answer. 
Result so far: 166.0
Subtract 3234 from 3701 to get 467.
Take the next digit (0) from the dividend and append it to 467, then repeat: 4670 / 539

Step 6:
When dividing 4670 by 539, we get 8 with a remainder of 358.
Write down 8 as next digit of the result. 
Result so far: 1668.0
The remainder is 358 after subtracting 4312 from 4670.
Take the next digit (7) from the dividend and append it to 358, then repeat: 3587 / 539

Let's proceed to step 7:
539 goes into 3587 6 times with a remainder of 353.
Use 6 as the next digit of our solution. 
Result so far: 16686.0
Subtract 3234 from 3587 to get 353.
Bring next digit (3) of the dividend behind the 353 and repeat the process: 3533 / 539

Moving on to step 8:
539 can be fit into 3533 6 times, resulting in a remainder of 299.
The next digit of our result is 6. 
Result so far: 166866.0
If we take 3234 away from 3533, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 9:
If we divide 2990 by 539, we get 5 and a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 166866.5
Subtract 2695 from 2990 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 10:
539 can be fit into 2950 5 times, resulting in a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 166866.55
Subtract 2695 from 2950 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final result is 166866.55 with a remainder of 0.255.
