Let's divide 289501 by 86
The aim is to understand the frequency of 86 in 289501.

Advancing to step 1:
The number 86 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 86

Going ahead to step 2:
If we divide 28 by 86, we get 0 and a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 86

On to step 3:
86 can be fit into 289 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 258 from 289 and we're left with 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 86

Going ahead to step 4:
If we divide 315 by 86, we get 3 and a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 57 after subtracting 258 from 315.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 86

Let's proceed to step 5:
When dividing 570 by 86, we get 6 with a remainder of 54.
The next digit of our result is 6. 
Result so far: 336.0
If we subtract 516 from 570, we get 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 86

Moving on to step 6:
The number 86 fits into 541 6 times, leaving a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 3366.0
Deduct 516 from 541 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
When dividing 250 by 86, we get 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 3366.2
The remainder is 78 after subtracting 172 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 8:
780 divided by 86 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 3366.29
Subtract 774 from 780 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
86 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 3366.29
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
86 goes into 600 6 times with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 3366.2906
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 3366.29069
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 3366.290697
Deduct 602 from 660 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
The number 86 fits into 580 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 3366.2906976
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 3366.29069767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 3366.29069767 with a remainder of 3.8e-08.
