543131 divided by 52 
The aim is to understand the frequency of 52 in 543131.

Going ahead to step 1:
52 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 52

Let's proceed to step 2:
54 divided by 52 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 52 from 54 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 52

Advancing to step 3:
52 goes into 23 0 times with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 23, we end up with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 52

Step 4:
The number 52 fits into 231 4 times, leaving a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Deduct 208 from 231 and we're left with 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 52

Going ahead to step 5:
The number 52 fits into 233 4 times, leaving a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 1044.0
The remainder is 25 after subtracting 208 from 233.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 52

Step 6:
If we divide 251 by 52, we get 4 and a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 10444.0
If we take 208 away from 251, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
52 can be fit into 430 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 10444.8
If we subtract 416 from 430, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
If we divide 140 by 52, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 10444.82
Subtracting 104 from 140 leaves us with 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 9:
The number 52 fits into 360 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 10444.826
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.

Advancing to step 10:
480 divided by 52 is 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 10444.8269
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
120 divided by 52 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 10444.82692
Subtracting 104 from 120 leaves us with 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 12:
The number 52 fits into 160 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 10444.826923
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
The number 52 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 10444.826923
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
The number 52 fits into 400 7 times, leaving a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 10444.82692307
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 10444.82692307 with a remainder of 3.6e-08.
