Let's divide 139875 by 52
The aim is to understand the frequency of 52 in 139875.

Step 1:
The number 52 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 52

Let's proceed to step 2:
13 divided by 52 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 52

Moving on to step 3:
52 goes into 139 2 times with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 104 from 139 leaves us with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 52

Moving on to step 4:
When dividing 358 by 52, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 312 from 358 leaves us with 46.
Include the next digit (7) from the dividend after 46, then repeat: 467 / 52

Advancing to step 5:
If we divide 467 by 52, we get 8 and a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 268.0
The remainder is 51 after subtracting 416 from 467.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 52

Advancing to step 6:
If we divide 515 by 52, we get 9 and a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 2689.0
The remainder is 47 after subtracting 468 from 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
52 can be fit into 470 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 2689.9
Subtract 468 from 470 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 52, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2689.9
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 52, we get 3 and a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 2689.903
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
52 goes into 440 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 2689.9038
If we subtract 416 from 440, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 52, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 2689.90384
The remainder is 32 after subtracting 208 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
320 divided by 52 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 2689.903846
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
When dividing 80 by 52, we get 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 2689.9038461
Subtract 52 from 80 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
The number 52 fits into 280 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 2689.90384615
Subtracting 260 from 280 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 2689.90384615 with a remainder of 2e-08.
