112804 divided by 86 
The aim is to understand the frequency of 86 in 112804.

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 (1) from the dividend, attach it to 1 and continue: 11 / 86

Advancing to step 2:
86 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 86

Advancing to step 3:
112 divided by 86 is 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 86 from 112 to get 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 86

Step 4:
The number 86 fits into 268 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 10 after subtracting 258 from 268.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 86

Moving on to step 5:
When dividing 100 by 86, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 131.0
The remainder is 14 after subtracting 86 from 100.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 86

Going ahead to step 6:
The number 86 fits into 144 1 times, leaving a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 1311.0
If we take 86 away from 144, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 1311.6
If we take 516 away from 580, we end up 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.

Let's proceed to step 8:
The number 86 fits into 640 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 1311.67
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 1311.674
Subtract 344 from 380 to get 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 10:
86 can be fit into 360 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1311.6744
If we subtract 344 from 360, we 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 1311.6744 with a remainder of 0.00016.
