84443891 ÷ 539 
The aim is to understand the frequency of 539 in 84443891.

Moving on to step 1:
539 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 539

Advancing to step 2:
If we divide 84 by 539, we get 0 and a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 539

On to step 3:
If we divide 844 by 539, we get 1 and a remainder of 305.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 305 after subtracting 539 from 844.
Include the next digit (4) from the dividend after 305, then repeat: 3054 / 539

Moving on to step 4:
3054 divided by 539 is 5 with a remainder of 359.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 2695 from 3054 and we're left with 359.
Fetch the next digit (3) from the dividend, attach it to 359 and continue: 3593 / 539

Moving on to step 5:
539 can be fit into 3593 6 times, resulting in a remainder of 359.
Write down 6 as next digit of the result. 
Result so far: 156.0
Deduct 3234 from 3593 and we're left with 359.
Include the next digit (8) from the dividend after 359, then repeat: 3598 / 539

Step 6:
539 goes into 3598 6 times with a remainder of 364.
Put 6 as the next digit of the answer. 
Result so far: 1566.0
The remainder is 364 after subtracting 3234 from 3598.
Include the next digit (9) from the dividend after 364, then repeat: 3649 / 539

Advancing to step 7:
539 goes into 3649 6 times with a remainder of 415.
Write down 6 as next digit of the result. 
Result so far: 15666.0
Subtracting 3234 from 3649 leaves us with 415.
Bring next digit (1) of the dividend behind the 415 and repeat the process: 4151 / 539

Moving on to step 8:
When dividing 4151 by 539, we get 7 with a remainder of 378.
Record the quotient 7 as the next digit in the result. 
Result so far: 156667.0
Subtract 3773 from 4151 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 9:
The number 539 fits into 3780 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 156667.7
Deduct 3773 from 3780 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
539 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 156667.7
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
If we divide 700 by 539, we get 1 and a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 156667.701
Subtracting 539 from 700 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 12:
1610 divided by 539 is 2 with a remainder of 532.
The next digit of our result is 2. 
Result so far: 156667.7012
Deduct 1078 from 1610 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Advancing to step 13:
If we divide 5320 by 539, we get 9 and a remainder of 469.
The number 9 becomes the next digit in our result. 
Result so far: 156667.70129
The remainder is 469 after subtracting 4851 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

On to step 14:
If we divide 4690 by 539, we get 8 and a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 156667.701298
If we subtract 4312 from 4690, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 15:
If we divide 3780 by 539, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 156667.7012987
Deduct 3773 from 3780 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 16:
The number 539 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 156667.7012987
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 156667.7012987 and a remainder of 7e-08.
