323415 divided by 86 
The aim is to understand the frequency of 86 in 323415.

Moving on to step 1:
3 divided by 86 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 86

Going ahead to step 2:
When dividing 32 by 86, we get 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 86

On to step 3:
When dividing 323 by 86, we get 3 with a remainder of 65.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 258 from 323 to get 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 86

On to step 4:
The number 86 fits into 654 7 times, leaving a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 52 after subtracting 602 from 654.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 86

Let's proceed to step 5:
86 goes into 521 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 376.0
Subtracting 516 from 521 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 86

On to step 6:
The number 86 fits into 55 0 times, leaving a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 3760.0
Subtracting 0 from 55 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
If we divide 550 by 86, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 3760.6
Subtract 516 from 550 to 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.

On to step 8:
The number 86 fits into 340 3 times, leaving a remainder of 82.
The next digit of our result is 3. 
Result so far: 3760.63
Deduct 258 from 340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 9:
86 goes into 820 9 times with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 3760.639
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
If we divide 460 by 86, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3760.6395
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 11:
If we divide 300 by 86, we get 3 and a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 3760.63953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 3760.639534
Deduct 344 from 420 and we're left 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.

Moving on to step 13:
760 divided by 86 is 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 3760.6395348
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.

Step 14:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 3760.63953488
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 3760.63953488, and the remainder is 3.2e-08.
