We look at the division of 802702 by 52 
The aim is to understand the frequency of 52 in 802702.

Advancing to step 1:
52 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 52

Let's proceed to step 2:
If we divide 80 by 52, we get 1 and a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 52 away from 80, we end up with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 52

Step 3:
52 goes into 282 5 times with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 260 from 282, we get 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 52

Step 4:
52 goes into 227 4 times with a remainder of 19.
The next digit of our result is 4. 
Result so far: 154.0
Subtracting 208 from 227 leaves us with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 52

On to step 5:
If we divide 190 by 52, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 1543.0
If we subtract 156 from 190, we get 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 52

On to step 6:
If we divide 342 by 52, we get 6 and a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 15436.0
Deduct 312 from 342 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
300 divided by 52 is 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 15436.5
If we subtract 260 from 300, 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.

Step 8:
52 goes into 400 7 times with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 15436.57
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.

Advancing to step 9:
If we divide 360 by 52, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 15436.576
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
When dividing 480 by 52, we get 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 15436.5769
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.

Let's proceed to step 11:
120 divided by 52 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 15436.57692
The remainder is 16 after subtracting 104 from 120.
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 12:
52 goes into 160 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 15436.576923
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.

Step 13:
If we divide 40 by 52, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 15436.576923
Subtract 0 from 40 to 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.

On to step 14:
The number 52 fits into 400 7 times, leaving a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 15436.57692307
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.

The quotient of the division is 15436.57692307, and the remainder is 3.6e-08.
