We're dividing 252876 by 87 
The aim is to understand the frequency of 87 in 252876.

Advancing to step 1:
87 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 87

Let's proceed to step 2:
87 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 87

Moving on to step 3:
87 goes into 252 2 times with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 174 from 252, we get 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 87

On to step 4:
788 divided by 87 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 5 after subtracting 783 from 788.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 87

Let's proceed to step 5:
87 goes into 57 0 times with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 290.0
If we take 0 away from 57, we end up with 57.
Include the next digit (6) from the dividend after 57, then repeat: 576 / 87

Advancing to step 6:
The number 87 fits into 576 6 times, leaving a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 2906.0
Subtract 522 from 576 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
The number 87 fits into 540 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 2906.6
If we subtract 522 from 540, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
87 can be fit into 180 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2906.62
The remainder is 6 after subtracting 174 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
When dividing 60 by 87, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 2906.62
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
87 goes into 600 6 times with a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 2906.6206
The remainder is 78 after subtracting 522 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
If we divide 780 by 87, we get 8 and a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 2906.62068
Deduct 696 from 780 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
If we divide 840 by 87, we get 9 and a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 2906.620689
If we subtract 783 from 840, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 13:
The number 87 fits into 570 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 2906.6206896
Subtracting 522 from 570 leaves us 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.

Step 14:
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: 2906.62068965
Subtracting 435 from 480 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 2906.62068965 and a remainder of 4.5e-08.
