We're dividing 818052 by 52 
The aim is to understand the frequency of 52 in 818052.

Let's proceed to step 1:
The number 52 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 52

Going ahead to step 2:
If we divide 81 by 52, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 52 from 81 leaves us with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 52

Advancing to step 3:
If we divide 298 by 52, we get 5 and a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 260 from 298 leaves us with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 52

On to step 4:
52 goes into 380 7 times with a remainder of 16.
The next digit of our result is 7. 
Result so far: 157.0
Subtract 364 from 380 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 52

Let's proceed to step 5:
If we divide 165 by 52, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 1573.0
If we subtract 156 from 165, we get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 52

On to step 6:
When dividing 92 by 52, we get 1 with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 15731.0
If we take 52 away from 92, we end up 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.

On to step 7:
If we divide 400 by 52, we get 7 and a remainder of 36.
The next digit of our result is 7. 
Result so far: 15731.7
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.

Let's proceed to step 8:
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: 15731.76
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.

Moving on to step 9:
480 divided by 52 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 15731.769
Subtracting 468 from 480 leaves us 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.

Advancing to step 10:
When dividing 120 by 52, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 15731.7692
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.

Going ahead to step 11:
52 goes into 160 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 15731.76923
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.

Advancing to step 12:
The number 52 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 15731.76923
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.

Advancing to step 13:
If we divide 400 by 52, we get 7 and a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 15731.7692307
If we take 364 away from 400, we end up 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.

Step 14:
The number 52 fits into 360 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 15731.76923076
Subtracting 312 from 360 leaves us 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.

The final outcome is 15731.76923076, with a leftover of 4.8e-08.
