We look at the division of 443529 by 52 
The aim is to understand the frequency of 52 in 443529.

Advancing to step 1:
52 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 52

Let's proceed to step 2:
When dividing 44 by 52, we get 0 with a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 52

On to step 3:
If we divide 443 by 52, we get 8 and a remainder of 27.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 416 from 443, we get 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 52

Moving on to step 4:
52 goes into 275 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Deduct 260 from 275 and we're left with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 52

Moving on to step 5:
When dividing 152 by 52, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 852.0
The remainder is 48 after subtracting 104 from 152.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 52

Step 6:
52 goes into 489 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 8529.0
Subtract 468 from 489 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
52 goes into 210 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 8529.4
If we subtract 208 from 210, we 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.

Moving on to step 8:
52 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8529.4
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.

Moving on to step 9:
52 goes into 200 3 times with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 8529.403
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.

Let's proceed to step 10:
The number 52 fits into 440 8 times, leaving a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 8529.4038
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.

Step 11:
The number 52 fits into 240 4 times, leaving a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 8529.40384
Subtracting 208 from 240 leaves us 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.

Step 12:
If we divide 320 by 52, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 8529.403846
Subtracting 312 from 320 leaves us 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.

Advancing to step 13:
The number 52 fits into 80 1 times, leaving a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 8529.4038461
Deduct 52 from 80 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
280 divided by 52 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 8529.40384615
If we subtract 260 from 280, we 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.

Our division results in 8529.40384615 with a remaining 2e-08.
