Let's divide 23709 by 86
The aim is to understand the frequency of 86 in 23709.

Let's proceed to step 1:
When dividing 2 by 86, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 86

Advancing to step 2:
If we divide 23 by 86, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 86

Advancing to step 3:
237 divided by 86 is 2 with a remainder of 65.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 65 after subtracting 172 from 237.
Grab the next digit (0) from the dividend, add it to 65, then carry on: 650 / 86

Moving on to step 4:
When dividing 650 by 86, we get 7 with a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 602 away from 650, we end up with 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 86

On to step 5:
86 can be fit into 489 5 times, resulting in a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 275.0
Subtract 430 from 489 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 6:
590 divided by 86 is 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 275.6
The remainder is 74 after subtracting 516 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 7:
740 divided by 86 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 275.68
Subtracting 688 from 740 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
520 divided by 86 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 275.686
Subtracting 516 from 520 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 275.686
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 86 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 275.68604
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 275.686046
If we take 516 away from 560, we end up with 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 12:
86 goes into 440 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 275.6860465
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
86 can be fit into 100 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 275.68604651
If we take 86 away from 100, we end up 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.

Our division results in 275.68604651 with a remaining 1.4e-08.
