We look at the division of 85937551 by 539 
The aim is to understand the frequency of 539 in 85937551.

Step 1:
8 divided by 539 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 539

Advancing to step 2:
539 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 539

Going ahead to step 3:
If we divide 859 by 539, we get 1 and a remainder of 320.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 539 from 859 leaves us with 320.
Append the next digit (3) from the dividend to 320 and continue with: 3203 / 539

On to step 4:
When dividing 3203 by 539, we get 5 with a remainder of 508.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2695 away from 3203, we end up with 508.
Take the next digit (7) from the dividend and append it to 508, then repeat: 5087 / 539

On to step 5:
The number 539 fits into 5087 9 times, leaving a remainder of 236.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we subtract 4851 from 5087, we get 236.
Append the next digit (5) from the dividend to 236 and continue with: 2365 / 539

On to step 6:
If we divide 2365 by 539, we get 4 and a remainder of 209.
The next digit of our result is 4. 
Result so far: 1594.0
Deduct 2156 from 2365 and we're left with 209.
Grab the next digit (5) from the dividend, add it to 209, then carry on: 2095 / 539

Going ahead to step 7:
2095 divided by 539 is 3 with a remainder of 478.
The next digit of our result is 3. 
Result so far: 15943.0
Subtract 1617 from 2095 to get 478.
Take the next digit (1) from the dividend and append it to 478, then repeat: 4781 / 539

Let's proceed to step 8:
If we divide 4781 by 539, we get 8 and a remainder of 469.
The next digit of our result is 8. 
Result so far: 159438.0
If we subtract 4312 from 4781, we get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Advancing to step 9:
539 goes into 4690 8 times with a remainder of 378.
Write down 8 as next digit of the result. 
Result so far: 159438.8
Deduct 4312 from 4690 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 10:
When dividing 3780 by 539, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 159438.87
If we take 3773 away from 3780, we end up 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 11:
70 divided by 539 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 159438.87
Subtract 0 from 70 to 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.

Let's proceed to step 12:
539 can be fit into 700 1 times, resulting in a remainder of 161.
The number 1 becomes the next digit in our result. 
Result so far: 159438.8701
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.

Step 13:
If we divide 1610 by 539, we get 2 and a remainder of 532.
Write down 2 as next digit of the result. 
Result so far: 159438.87012
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.

On to step 14:
539 can be fit into 5320 9 times, resulting in a remainder of 469.
Use 9 as the next digit of our solution. 
Result so far: 159438.870129
Subtracting 4851 from 5320 leaves us with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Moving on to step 15:
4690 divided by 539 is 8 with a remainder of 378.
Record the quotient 8 as the next digit in the result. 
Result so far: 159438.8701298
If we take 4312 away from 4690, we end up with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 16:
When dividing 3780 by 539, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 159438.87012987
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.

In conclusion, the division gives 159438.87012987 with a balance of 7e-09.
