We look at the division of 38259 by 87 
The aim is to understand the frequency of 87 in 38259.

Going ahead to step 1:
When dividing 3 by 87, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 87

Let's proceed to step 2:
87 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 87

Let's proceed to step 3:
382 divided by 87 is 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 348 from 382 leaves us with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 87

Going ahead to step 4:
When dividing 345 by 87, we get 3 with a remainder of 84.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 84 after subtracting 261 from 345.
Fetch the next digit (9) from the dividend, attach it to 84 and continue: 849 / 87

On to step 5:
87 can be fit into 849 9 times, resulting in a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 439.0
The remainder is 66 after subtracting 783 from 849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 6:
When dividing 660 by 87, we get 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 439.7
If we subtract 609 from 660, we get 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:
When dividing 510 by 87, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 439.75
If we subtract 435 from 510, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 8:
When dividing 750 by 87, we get 8 with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 439.758
If we subtract 696 from 750, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
87 goes into 540 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 439.7586
If we subtract 522 from 540, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
The number 87 fits into 180 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 439.75862
If we take 174 away from 180, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
If we divide 60 by 87, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 439.75862
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
When dividing 600 by 87, we get 6 with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 439.7586206
If we take 522 away from 600, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 13:
When dividing 780 by 87, we get 8 with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 439.75862068
Deduct 696 from 780 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 439.75862068, with a leftover of 8.4e-08.
