Let's divide 116571 by 86
The aim is to understand the frequency of 86 in 116571.

Moving on to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 86

Moving on to step 2:
When dividing 11 by 86, we get 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 86

Moving on to step 3:
When dividing 116 by 86, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 86 away from 116, we end up with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 86

Step 4:
86 goes into 305 3 times with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 258 from 305, we get 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 86

Step 5:
86 can be fit into 477 5 times, resulting in a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 135.0
If we take 430 away from 477, we end up with 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 86

Step 6:
When dividing 471 by 86, we get 5 with a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 1355.0
Subtracting 430 from 471 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
86 goes into 410 4 times with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 1355.4
Subtract 344 from 410 to 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.

On to step 8:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 1355.47
If we subtract 602 from 660, we get 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 9:
86 can be fit into 580 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 1355.476
Subtracting 516 from 580 leaves us 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 10:
86 can be fit into 640 7 times, resulting in a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 1355.4767
Subtracting 602 from 640 leaves us 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.

Going ahead to step 11:
380 divided by 86 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 1355.47674
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
86 goes into 360 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1355.476744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 1355.476744 with a remainder of 1.6e-06.
