We look at the division of 788486 by 52 
The aim is to understand the frequency of 52 in 788486.

Let's proceed to step 1:
The number 52 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 52

Going ahead to step 2:
52 can be fit into 78 1 times, resulting in a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 52 from 78, we get 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 52

Going ahead to step 3:
52 can be fit into 268 5 times, resulting in a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 260 from 268, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 52

Going ahead to step 4:
The number 52 fits into 84 1 times, leaving a remainder of 32.
The next digit of our result is 1. 
Result so far: 151.0
If we take 52 away from 84, we end up with 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 52

Moving on to step 5:
The number 52 fits into 328 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 1516.0
If we subtract 312 from 328, we get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 52

On to step 6:
166 divided by 52 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 15163.0
Subtract 156 from 166 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
When dividing 100 by 52, we get 1 with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 15163.1
The remainder is 48 after subtracting 52 from 100.
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 8:
When dividing 480 by 52, we get 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 15163.19
Deduct 468 from 480 and we're left 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 9:
The number 52 fits into 120 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 15163.192
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.

Step 10:
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: 15163.1923
Deduct 156 from 160 and we're left 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.

Moving on to step 11:
When dividing 40 by 52, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 15163.1923
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.

Moving on to step 12:
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: 15163.192307
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 13:
52 goes into 360 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 15163.1923076
If we take 312 away from 360, we end up 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.

Step 14:
52 goes into 480 9 times with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 15163.19230769
Deduct 468 from 480 and we're left 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 15163.19230769 with a remainder of 1.2e-08.
