545791 ÷ 52 
The aim is to understand the frequency of 52 in 545791.

Moving on to step 1:
The number 52 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 52

Moving on to step 2:
When dividing 54 by 52, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 52 from 54 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 52

Going ahead to step 3:
25 divided by 52 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 25, we end up with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 52

Step 4:
52 can be fit into 257 4 times, resulting in a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
The remainder is 49 after subtracting 208 from 257.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 52

On to step 5:
The number 52 fits into 499 9 times, leaving a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 1049.0
If we subtract 468 from 499, we get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 52

On to step 6:
52 can be fit into 311 5 times, resulting in a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 10495.0
Subtracting 260 from 311 leaves us 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.

On to step 7:
52 can be fit into 510 9 times, resulting in a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 10495.9
The remainder is 42 after subtracting 468 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
52 goes into 420 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 10495.98
Subtract 416 from 420 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.

On to step 9:
40 divided by 52 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10495.98
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.

Going ahead to step 10:
52 can be fit into 400 7 times, resulting in a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 10495.9807
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
The number 52 fits into 360 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 10495.98076
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.
Write down 9 as next digit of the result. 
Result so far: 10495.980769
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.

Moving on to step 13:
If we divide 120 by 52, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 10495.9807692
If we subtract 104 from 120, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
When dividing 160 by 52, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 10495.98076923
If we take 156 away from 160, 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.

Our division results in 10495.98076923 with a remaining 4e-09.
