641783 ÷ 52 
The aim is to understand the frequency of 52 in 641783.

Let's proceed to step 1:
The number 52 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 52

Moving on to step 2:
52 can be fit into 64 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we take 52 away from 64, we end up with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 52

On to step 3:
If we divide 121 by 52, we get 2 and a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 104 from 121 and we're left with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 52

On to step 4:
52 can be fit into 177 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 123.0
If we take 156 away from 177, we end up with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 52

Let's proceed to step 5:
52 can be fit into 218 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 1234.0
If we take 208 away from 218, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 52

On to step 6:
If we divide 103 by 52, we get 1 and a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 12341.0
If we take 52 away from 103, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 7:
510 divided by 52 is 9 with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 12341.9
If we take 468 away from 510, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
52 goes into 420 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 12341.98
If we take 416 away from 420, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
52 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 12341.98
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
52 can be fit into 400 7 times, resulting in a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 12341.9807
Subtracting 364 from 400 leaves us with 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 11:
52 goes into 360 6 times with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 12341.98076
Deduct 312 from 360 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.

Going ahead to step 12:
480 divided by 52 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 12341.980769
If we take 468 away from 480, we end up 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 13:
52 goes into 120 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 12341.9807692
Deduct 104 from 120 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
52 goes into 160 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 12341.98076923
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 12341.98076923 with a remaining 4e-09.
