We look at the division of 67891 by 52 
The aim is to understand the frequency of 52 in 67891.

Step 1:
52 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 52

On to step 2:
52 goes into 67 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 52 from 67 and we're left with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 52

Let's proceed to step 3:
If we divide 158 by 52, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 156 from 158, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 52

Moving on to step 4:
When dividing 29 by 52, we get 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 52

Moving on to step 5:
If we divide 291 by 52, we get 5 and a remainder of 31.
The next digit of our result is 5. 
Result so far: 1305.0
If we subtract 260 from 291, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 6:
If we divide 310 by 52, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1305.5
If we subtract 260 from 310, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
52 goes into 500 9 times with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 1305.59
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
52 can be fit into 320 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1305.596
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
52 goes into 80 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1305.5961
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.

Going ahead to step 10:
52 can be fit into 280 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1305.59615
The remainder is 20 after subtracting 260 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
52 can be fit into 200 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 1305.596153
Deduct 156 from 200 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
52 can be fit into 440 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 1305.5961538
The remainder is 24 after subtracting 416 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
52 can be fit into 240 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 1305.59615384
If we take 208 away from 240, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 1305.59615384 with a remainder of 3.2e-08.
