We look at the division of 356213 by 52 
The aim is to understand the frequency of 52 in 356213.

Let's proceed to step 1:
3 divided by 52 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 52

Step 2:
The number 52 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 52

On to step 3:
The number 52 fits into 356 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 312 from 356, we get 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 52

On to step 4:
52 goes into 442 8 times with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 416 from 442 leaves us with 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 52

Advancing to step 5:
If we divide 261 by 52, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 685.0
The remainder is 1 after subtracting 260 from 261.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 52

Advancing to step 6:
52 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 6850.0
Deduct 0 from 13 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
52 goes into 130 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 6850.2
If we subtract 104 from 130, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
52 can be fit into 260 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6850.25
The remainder is 0 after subtracting 260 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
52 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6850.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 52 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6850.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 6850.25 with a balance of 0.0.
