We're dividing 75027 by 87 
The aim is to understand the frequency of 87 in 75027.

Going ahead to step 1:
The number 87 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 87

Advancing to step 2:
75 divided by 87 is 0 with a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Include the next digit (0) from the dividend after 75, then repeat: 750 / 87

Step 3:
87 goes into 750 8 times with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 54 after subtracting 696 from 750.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 87

Let's proceed to step 4:
542 divided by 87 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 20 after subtracting 522 from 542.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 87

Going ahead to step 5:
If we divide 207 by 87, we get 2 and a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 862.0
If we take 174 away from 207, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 6:
330 divided by 87 is 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 862.3
Subtracting 261 from 330 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
87 can be fit into 690 7 times, resulting in a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 862.37
If we take 609 away from 690, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 8:
If we divide 810 by 87, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 862.379
Subtract 783 from 810 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
When dividing 270 by 87, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 862.3793
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
87 goes into 90 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 862.37931
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
87 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 862.37931
Subtract 0 from 30 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.

Step 12:
When dividing 300 by 87, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 862.3793103
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 13:
If we divide 390 by 87, we get 4 and a remainder of 42.
The next digit of our result is 4. 
Result so far: 862.37931034
Deduct 348 from 390 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.

The final outcome is 862.37931034, with a leftover of 4.2e-08.
