523014 divided by 87 
The aim is to understand the frequency of 87 in 523014.

Moving on to step 1:
The number 87 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 87

Going ahead to step 2:
52 divided by 87 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 87

Advancing to step 3:
87 goes into 523 6 times with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 522 away from 523, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 87

On to step 4:
87 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 60.0
Deduct 0 from 10 and we're left with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 87

Moving on to step 5:
The number 87 fits into 101 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 601.0
Subtract 87 from 101 to get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 87

Moving on to step 6:
87 can be fit into 144 1 times, resulting in a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 6011.0
The remainder is 57 after subtracting 87 from 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
87 can be fit into 570 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 6011.6
Deduct 522 from 570 and we're left 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.

Let's proceed to step 8:
87 can be fit into 480 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 6011.65
The remainder is 45 after subtracting 435 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
450 divided by 87 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 6011.655
The remainder is 15 after subtracting 435 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 6011.655 with a remainder of 0.0015.
