We divide 15228 by 87
The aim is to understand the frequency of 87 in 15228.

Going ahead to step 1:
If we divide 1 by 87, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 87

On to step 2:
The number 87 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 87

Advancing to step 3:
87 goes into 152 1 times with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 87 away from 152, we end up with 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 87

Advancing to step 4:
The number 87 fits into 652 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 609 from 652 leaves us with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 87

Moving on to step 5:
438 divided by 87 is 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
The remainder is 3 after subtracting 435 from 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
87 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 175.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
87 goes into 300 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 175.03
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.

Step 8:
If we divide 390 by 87, we get 4 and a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 175.034
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
87 goes into 420 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 175.0344
Subtracting 348 from 420 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 175.0344 with a balance of 0.00072.
