We're dividing 85806218 by 539 
The aim is to understand the frequency of 539 in 85806218.

Advancing to step 1:
The number 539 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 539

Step 2:
The number 539 fits into 85 0 times, leaving a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 539

Advancing to step 3:
If we divide 858 by 539, we get 1 and a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 539 from 858 and we're left with 319.
Take the next digit (0) from the dividend and append it to 319, then repeat: 3190 / 539

Moving on to step 4:
The number 539 fits into 3190 5 times, leaving a remainder of 495.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 495 after subtracting 2695 from 3190.
Grab the next digit (6) from the dividend, add it to 495, then carry on: 4956 / 539

Let's proceed to step 5:
If we divide 4956 by 539, we get 9 and a remainder of 105.
Use 9 as the next digit of our solution. 
Result so far: 159.0
If we subtract 4851 from 4956, we get 105.
Bring next digit (2) of the dividend behind the 105 and repeat the process: 1052 / 539

Let's proceed to step 6:
539 can be fit into 1052 1 times, resulting in a remainder of 513.
Put 1 as the next digit of the answer. 
Result so far: 1591.0
The remainder is 513 after subtracting 539 from 1052.
Bring next digit (1) of the dividend behind the 513 and repeat the process: 5131 / 539

Let's proceed to step 7:
When dividing 5131 by 539, we get 9 with a remainder of 280.
Write down 9 as next digit of the result. 
Result so far: 15919.0
If we take 4851 away from 5131, we end up with 280.
Bring next digit (8) of the dividend behind the 280 and repeat the process: 2808 / 539

Moving on to step 8:
The number 539 fits into 2808 5 times, leaving a remainder of 113.
Record the quotient 5 as the next digit in the result. 
Result so far: 159195.0
If we subtract 2695 from 2808, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 9:
539 goes into 1130 2 times with a remainder of 52.
The next digit of our result is 2. 
Result so far: 159195.2
Subtract 1078 from 1130 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
When dividing 520 by 539, we get 0 with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 159195.2
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 11:
The number 539 fits into 5200 9 times, leaving a remainder of 349.
Use 9 as the next digit of our solution. 
Result so far: 159195.209
Deduct 4851 from 5200 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 12:
When dividing 3490 by 539, we get 6 with a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 159195.2096
Subtracting 3234 from 3490 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 13:
If we divide 2560 by 539, we get 4 and a remainder of 404.
Write down 4 as next digit of the result. 
Result so far: 159195.20964
If we take 2156 away from 2560, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 14:
When dividing 4040 by 539, we get 7 with a remainder of 267.
Put 7 as the next digit of the answer. 
Result so far: 159195.209647
If we subtract 3773 from 4040, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 15:
539 can be fit into 2670 4 times, resulting in a remainder of 514.
Put 4 as the next digit of the answer. 
Result so far: 159195.2096474
Deduct 2156 from 2670 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 16:
539 goes into 5140 9 times with a remainder of 289.
Use 9 as the next digit of our solution. 
Result so far: 159195.20964749
Subtracting 4851 from 5140 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

The final outcome is 159195.20964749, with a leftover of 2.89e-07.
