Let's divide 287504 by 52
The aim is to understand the frequency of 52 in 287504.

On to step 1:
2 divided by 52 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 52

Let's proceed to step 2:
52 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 52

Advancing to step 3:
52 goes into 287 5 times with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 260 from 287 and we're left with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 52

Advancing to step 4:
The number 52 fits into 275 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Deduct 260 from 275 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 52

Advancing to step 5:
When dividing 150 by 52, we get 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 552.0
Subtract 104 from 150 to get 46.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 52

On to step 6:
464 divided by 52 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 5528.0
Deduct 416 from 464 and we're left 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.

Advancing to step 7:
480 divided by 52 is 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 5528.9
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
52 goes into 120 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 5528.92
Subtract 104 from 120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
160 divided by 52 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 5528.923
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
52 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 5528.923
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 52 is 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 5528.92307
Subtract 364 from 400 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
52 goes into 360 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 5528.923076
If we subtract 312 from 360, we get 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 13:
The number 52 fits into 480 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 5528.9230769
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
120 divided by 52 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 5528.92307692
Subtract 104 from 120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 5528.92307692, with a leftover of 1.6e-08.
