180524 divided by 86 
The aim is to understand the frequency of 86 in 180524.

Step 1:
86 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 86

Going ahead to step 2:
If we divide 18 by 86, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 86

Step 3:
180 divided by 86 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 172 from 180 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 86

Advancing to step 4:
If we divide 85 by 86, we get 0 and a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 85 to get 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 86

Step 5:
86 can be fit into 852 9 times, resulting in a remainder of 78.
Use 9 as the next digit of our solution. 
Result so far: 209.0
Deduct 774 from 852 and we're left with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 86

Let's proceed to step 6:
When dividing 784 by 86, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 2099.0
If we take 774 away from 784, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 2099.1
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
86 can be fit into 140 1 times, resulting in a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 2099.11
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 2099.11 with a balance of 0.054.
