Let's divide 178815 by 87
The aim is to understand the frequency of 87 in 178815.

Advancing to step 1:
The number 87 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 87

Step 2:
87 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 87

On to step 3:
If we divide 178 by 87, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 4 after subtracting 174 from 178.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 87

Moving on to step 4:
The number 87 fits into 48 0 times, leaving a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 48 and we're left with 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 87

Step 5:
87 can be fit into 481 5 times, resulting in a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 205.0
Deduct 435 from 481 and we're left with 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 87

Moving on to step 6:
87 can be fit into 465 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 2055.0
Subtract 435 from 465 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.

Let's proceed to step 7:
300 divided by 87 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 2055.3
Subtract 261 from 300 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 8:
87 goes into 390 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 2055.34
Subtracting 348 from 390 leaves us 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.

Advancing to step 9:
87 can be fit into 420 4 times, resulting in a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 2055.344
Deduct 348 from 420 and we're left 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.

The final outcome is 2055.344, with a leftover of 0.0072.
