We're dividing 134537 by 86 
The aim is to understand the frequency of 86 in 134537.

Going ahead to step 1:
When dividing 1 by 86, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 86

Going ahead to step 2:
86 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 86

Going ahead to step 3:
The number 86 fits into 134 1 times, leaving a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 86 from 134 leaves us with 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 86

Moving on to step 4:
The number 86 fits into 485 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 430 from 485 to get 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 86

Going ahead to step 5:
86 can be fit into 553 6 times, resulting in a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
Deduct 516 from 553 and we're left with 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 86

Going ahead to step 6:
If we divide 377 by 86, we get 4 and a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 1564.0
Deduct 344 from 377 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
If we divide 330 by 86, we get 3 and a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 1564.3
If we subtract 258 from 330, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 8:
720 divided by 86 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 1564.38
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
86 can be fit into 320 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 1564.383
Subtracting 258 from 320 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
620 divided by 86 is 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 1564.3837
Deduct 602 from 620 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
86 goes into 180 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 1564.38372
Subtract 172 from 180 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
86 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 1564.38372
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
The number 86 fits into 800 9 times, leaving a remainder of 26.
The next digit of our result is 9. 
Result so far: 1564.3837209
If we take 774 away from 800, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
If we divide 260 by 86, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1564.38372093
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 1564.38372093, with a leftover of 2e-09.
