Let's divide 43934804 by 539
The aim is to understand the frequency of 539 in 43934804.

Advancing to step 1:
When dividing 4 by 539, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 539

Moving on to step 2:
When dividing 43 by 539, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 539

Let's proceed to step 3:
The number 539 fits into 439 0 times, leaving a remainder of 439.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 439 and we're left with 439.
Append the next digit (3) from the dividend to 439 and continue with: 4393 / 539

Let's proceed to step 4:
4393 divided by 539 is 8 with a remainder of 81.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 4312 from 4393 leaves us with 81.
Append the next digit (4) from the dividend to 81 and continue with: 814 / 539

Step 5:
814 divided by 539 is 1 with a remainder of 275.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we take 539 away from 814, we end up with 275.
Append the next digit (8) from the dividend to 275 and continue with: 2758 / 539

Advancing to step 6:
539 goes into 2758 5 times with a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 815.0
Subtracting 2695 from 2758 leaves us with 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 539

Going ahead to step 7:
539 goes into 630 1 times with a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 8151.0
If we take 539 away from 630, we end up with 91.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 539

Step 8:
539 goes into 914 1 times with a remainder of 375.
The next digit of our result is 1. 
Result so far: 81511.0
If we subtract 539 from 914, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 9:
If we divide 3750 by 539, we get 6 and a remainder of 516.
The number 6 becomes the next digit in our result. 
Result so far: 81511.6
If we subtract 3234 from 3750, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 10:
When dividing 5160 by 539, we get 9 with a remainder of 309.
The next digit of our result is 9. 
Result so far: 81511.69
Deduct 4851 from 5160 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 11:
The number 539 fits into 3090 5 times, leaving a remainder of 395.
The next digit of our result is 5. 
Result so far: 81511.695
Subtract 2695 from 3090 to get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 12:
539 can be fit into 3950 7 times, resulting in a remainder of 177.
Use 7 as the next digit of our solution. 
Result so far: 81511.6957
If we take 3773 away from 3950, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 13:
1770 divided by 539 is 3 with a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 81511.69573
Deduct 1617 from 1770 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 14:
When dividing 1530 by 539, we get 2 with a remainder of 452.
Put 2 as the next digit of the answer. 
Result so far: 81511.695732
Deduct 1078 from 1530 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 15:
The number 539 fits into 4520 8 times, leaving a remainder of 208.
Record the quotient 8 as the next digit in the result. 
Result so far: 81511.6957328
The remainder is 208 after subtracting 4312 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 16:
The number 539 fits into 2080 3 times, leaving a remainder of 463.
The next digit of our result is 3. 
Result so far: 81511.69573283
Subtracting 1617 from 2080 leaves us with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

After the division, we end up with 81511.69573283 and a remainder of 4.63e-07.
