We divide 646926 by 52
The aim is to understand the frequency of 52 in 646926.

Step 1:
If we divide 6 by 52, we get 0 and 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.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 52

Advancing to step 2:
The number 52 fits into 64 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 52 from 64 leaves us with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 52

Going ahead to step 3:
126 divided by 52 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 104 from 126 and we're left with 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 52

Going ahead to step 4:
229 divided by 52 is 4 with a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we subtract 208 from 229, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 52

Step 5:
The number 52 fits into 212 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 1244.0
If we take 208 away from 212, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 52

Step 6:
52 can be fit into 46 0 times, resulting in a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 12440.0
Subtract 0 from 46 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
When dividing 460 by 52, we get 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 12440.8
If we subtract 416 from 460, we 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.

Step 8:
52 can be fit into 440 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 12440.88
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.

The final result is 12440.88 with a remainder of 0.024.
