We're dividing 507623 by 86 
The aim is to understand the frequency of 86 in 507623.

Let's proceed to step 1:
The number 86 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 86

Advancing to step 2:
86 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 86

Moving on to step 3:
If we divide 507 by 86, we get 5 and a remainder of 77.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 430 from 507 leaves us with 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 86

Advancing to step 4:
86 goes into 776 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Subtracting 774 from 776 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 86

On to step 5:
The number 86 fits into 22 0 times, leaving a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 590.0
Deduct 0 from 22 and we're left with 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 86

Moving on to step 6:
The number 86 fits into 223 2 times, leaving a remainder of 51.
The next digit of our result is 2. 
Result so far: 5902.0
Subtracting 172 from 223 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
If we divide 510 by 86, we get 5 and a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 5902.5
Deduct 430 from 510 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
86 goes into 800 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 5902.59
If we subtract 774 from 800, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
The number 86 fits into 260 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 5902.593
Subtract 258 from 260 to get 2.
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 10:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5902.593
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
86 can be fit into 200 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 5902.59302
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.

Let's proceed to step 12:
When dividing 280 by 86, we get 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 5902.593023
Deduct 258 from 280 and we're left 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.

Going ahead to step 13:
86 can be fit into 220 2 times, resulting in a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 5902.5930232
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.

On to step 14:
480 divided by 86 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5902.59302325
If we subtract 430 from 480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 5902.59302325 with a balance of 5e-08.
