We look at the division of 23824324 by 86 
The aim is to understand the frequency of 86 in 23824324.

On to step 1:
If we divide 2 by 86, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 86

On to step 2:
When dividing 23 by 86, we get 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 86

Going ahead to step 3:
86 goes into 238 2 times with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 172 from 238 and we're left with 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 86

Advancing to step 4:
The number 86 fits into 662 7 times, leaving a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 602 from 662 and we're left with 60.
Grab the next digit (4) from the dividend, add it to 60, then carry on: 604 / 86

Step 5:
604 divided by 86 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 277.0
If we take 602 away from 604, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 86

Going ahead to step 6:
86 can be fit into 23 0 times, resulting in a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 2770.0
Subtract 0 from 23 to get 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 86

Step 7:
The number 86 fits into 232 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 27702.0
If we subtract 172 from 232, we get 60.
Take the next digit (4) from the dividend and append it to 60, then repeat: 604 / 86

Let's proceed to step 8:
The number 86 fits into 604 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 277027.0
The remainder is 2 after subtracting 602 from 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 277027.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
200 divided by 86 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 277027.02
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
280 divided by 86 is 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 277027.023
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
220 divided by 86 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 277027.0232
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
The number 86 fits into 480 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 277027.02325
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
500 divided by 86 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 277027.023255
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 277027.023255 with a remainder of 7e-06.
