Let's divide 25918864 by 86
The aim is to understand the frequency of 86 in 25918864.

Step 1:
86 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 86

Advancing to step 2:
86 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 86

Step 3:
If we divide 259 by 86, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 258 away from 259, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 86

Advancing to step 4:
If we divide 11 by 86, we get 0 and a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 11 to get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 86

On to step 5:
118 divided by 86 is 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 301.0
Deduct 86 from 118 and we're left with 32.
Append the next digit (8) from the dividend to 32 and continue with: 328 / 86

Let's proceed to step 6:
If we divide 328 by 86, we get 3 and a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 3013.0
The remainder is 70 after subtracting 258 from 328.
Bring next digit (6) of the dividend behind the 70 and repeat the process: 706 / 86

Step 7:
706 divided by 86 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 30138.0
Deduct 688 from 706 and we're left with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 86

Going ahead to step 8:
If we divide 184 by 86, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 301382.0
The remainder is 12 after subtracting 172 from 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 86, we get 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 301382.1
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
If we divide 340 by 86, we get 3 and a remainder of 82.
The next digit of our result is 3. 
Result so far: 301382.13
The remainder is 82 after subtracting 258 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 11:
When dividing 820 by 86, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 301382.139
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
The number 86 fits into 460 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 301382.1395
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
300 divided by 86 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 301382.13953
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 14:
86 goes into 420 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 301382.139534
If we take 344 away from 420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 15:
760 divided by 86 is 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 301382.1395348
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 16:
If we divide 720 by 86, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 301382.13953488
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.

The final result is 301382.13953488 with a remainder of 3.2e-08.
