We're dividing 290426 by 52 
The aim is to understand the frequency of 52 in 290426.

Going ahead to step 1:
2 divided by 52 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 52

Let's proceed to step 2:
If we divide 29 by 52, we get 0 and a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 52

Step 3:
If we divide 290 by 52, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 260 from 290 leaves us with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 52

Going ahead to step 4:
52 goes into 304 5 times with a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 55.0
The remainder is 44 after subtracting 260 from 304.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 52

Going ahead to step 5:
442 divided by 52 is 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 558.0
If we subtract 416 from 442, we get 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 52

Step 6:
266 divided by 52 is 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5585.0
Deduct 260 from 266 and we're left 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.

Moving on to step 7:
The number 52 fits into 60 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 5585.1
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
If we divide 80 by 52, we get 1 and a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 5585.11
Subtract 52 from 80 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 5585.11 and a remainder of 0.028.
