We're dividing 155296 by 87 
The aim is to understand the frequency of 87 in 155296.

Let's proceed to step 1:
If we divide 1 by 87, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 87

On to step 2:
The number 87 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 87

Moving on to step 3:
87 goes into 155 1 times with a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 87 from 155, we get 68.
Take the next digit (2) from the dividend and append it to 68, then repeat: 682 / 87

Step 4:
682 divided by 87 is 7 with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 73 after subtracting 609 from 682.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 87

Moving on to step 5:
When dividing 739 by 87, we get 8 with a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
Subtracting 696 from 739 leaves us with 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 87

On to step 6:
87 can be fit into 436 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 1785.0
Subtracting 435 from 436 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
87 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1785.0
If we take 0 away from 10, 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.

Let's proceed to step 8:
When dividing 100 by 87, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1785.01
If we subtract 87 from 100, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
The number 87 fits into 130 1 times, leaving a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 1785.011
The remainder is 43 after subtracting 87 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The quotient of the division is 1785.011, and the remainder is 0.0043.
