We look at the division of 722239 by 52 
The aim is to understand the frequency of 52 in 722239.

Let's proceed to step 1:
7 divided by 52 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 52

Step 2:
The number 52 fits into 72 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 52 from 72 to get 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 52

Advancing to step 3:
When dividing 202 by 52, we get 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 13.0
If we take 156 away from 202, we end up with 46.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 52

Step 4:
When dividing 462 by 52, we get 8 with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
The remainder is 46 after subtracting 416 from 462.
Fetch the next digit (3) from the dividend, attach it to 46 and continue: 463 / 52

Going ahead to step 5:
If we divide 463 by 52, we get 8 and a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 1388.0
The remainder is 47 after subtracting 416 from 463.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 52

Going ahead to step 6:
If we divide 479 by 52, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 13889.0
Deduct 468 from 479 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
110 divided by 52 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 13889.2
If we take 104 away from 110, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 52 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 13889.21
Deduct 52 from 60 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.

Step 9:
When dividing 80 by 52, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 13889.211
Subtracting 52 from 80 leaves us 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.

The final outcome is 13889.211, with a leftover of 0.0028.
