Let's divide 145987 by 52
The aim is to understand the frequency of 52 in 145987.

Advancing to step 1:
When dividing 1 by 52, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 52

Let's proceed to step 2:
If we divide 14 by 52, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 52

Going ahead to step 3:
52 can be fit into 145 2 times, resulting in a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 104 from 145 leaves us with 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 52

On to step 4:
419 divided by 52 is 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 416 from 419, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 52

Let's proceed to step 5:
52 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
If we take 0 away from 38, we end up with 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 52

Step 6:
387 divided by 52 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 2807.0
Subtracting 364 from 387 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
230 divided by 52 is 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 2807.4
If we take 208 away from 230, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
52 goes into 220 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 2807.44
The remainder is 12 after subtracting 208 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 2807.44 with a remainder of 0.012.
