We look at the division of 89755254 by 86 
The aim is to understand the frequency of 86 in 89755254.

Going ahead to step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 86

Step 2:
When dividing 89 by 86, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 3 after subtracting 86 from 89.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 86

Moving on to step 3:
The number 86 fits into 37 0 times, leaving a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 86

On to step 4:
When dividing 375 by 86, we get 4 with a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtract 344 from 375 to get 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 86

Step 5:
86 goes into 315 3 times with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 1043.0
If we subtract 258 from 315, we get 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 86

Going ahead to step 6:
When dividing 572 by 86, we get 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 10436.0
If we take 516 away from 572, we end up with 56.
Grab the next digit (5) from the dividend, add it to 56, then carry on: 565 / 86

Going ahead to step 7:
When dividing 565 by 86, we get 6 with a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 104366.0
The remainder is 49 after subtracting 516 from 565.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 86

Let's proceed to step 8:
86 goes into 494 5 times with a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 1043665.0
Subtract 430 from 494 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
640 divided by 86 is 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 1043665.7
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.

Advancing to step 10:
86 goes into 380 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1043665.74
If we take 344 away from 380, we end up 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.

Let's proceed to step 11:
360 divided by 86 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1043665.744
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 1043665.744 with a remaining 0.0016.
