Let's divide 16881426 by 86
The aim is to understand the frequency of 86 in 16881426.

Going ahead to step 1:
1 divided by 86 is 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 (6) from the dividend, attach it to 1 and continue: 16 / 86

Let's proceed to step 2:
16 divided by 86 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 86

Going ahead to step 3:
168 divided by 86 is 1 with a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 86 from 168 to get 82.
Append the next digit (8) from the dividend to 82 and continue with: 828 / 86

Going ahead to step 4:
86 can be fit into 828 9 times, resulting in a remainder of 54.
The next digit of our result is 9. 
Result so far: 19.0
If we take 774 away from 828, we end up with 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 86

Advancing to step 5:
When dividing 541 by 86, we get 6 with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
If we subtract 516 from 541, we get 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 86

Let's proceed to step 6:
254 divided by 86 is 2 with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 1962.0
Subtracting 172 from 254 leaves us with 82.
Include the next digit (2) from the dividend after 82, then repeat: 822 / 86

Moving on to step 7:
86 goes into 822 9 times with a remainder of 48.
The next digit of our result is 9. 
Result so far: 19629.0
Subtracting 774 from 822 leaves us with 48.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 86

Let's proceed to step 8:
86 can be fit into 486 5 times, resulting in a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 196295.0
The remainder is 56 after subtracting 430 from 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
86 can be fit into 560 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 196295.6
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
440 divided by 86 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 196295.65
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 86, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 196295.651
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
86 goes into 140 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 196295.6511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 196295.6511, with a leftover of 0.00054.
