We look at the division of 818048 by 52 
The aim is to understand the frequency of 52 in 818048.

Advancing to step 1:
When dividing 8 by 52, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 52

Let's proceed to step 2:
52 goes into 81 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 52 from 81 and we're left with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 52

Let's proceed to step 3:
298 divided by 52 is 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 260 from 298 to get 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 52

Step 4:
52 can be fit into 380 7 times, resulting in a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Subtract 364 from 380 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 52

Moving on to step 5:
When dividing 164 by 52, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 1573.0
If we subtract 156 from 164, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 52

Moving on to step 6:
If we divide 88 by 52, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 15731.0
Subtract 52 from 88 to 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.

Going ahead to step 7:
The number 52 fits into 360 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 15731.6
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.

On to step 8:
If we divide 480 by 52, we get 9 and a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 15731.69
Subtract 468 from 480 to 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.

Going ahead to step 9:
When dividing 120 by 52, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 15731.692
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.

Let's proceed to step 10:
The number 52 fits into 160 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 15731.6923
Subtract 156 from 160 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.

Let's proceed to step 11:
52 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 15731.6923
Deduct 0 from 40 and we're left 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.

Moving on to step 12:
The number 52 fits into 400 7 times, leaving a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 15731.692307
Subtract 364 from 400 to 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 13:
52 can be fit into 360 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 15731.6923076
The remainder is 48 after subtracting 312 from 360.
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 14:
If we divide 480 by 52, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 15731.69230769
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.

The final result is 15731.69230769 with a remainder of 1.2e-08.
