Let's divide 863665 by 52
The aim is to understand the frequency of 52 in 863665.

Step 1:
If we divide 8 by 52, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 52

Step 2:
52 can be fit into 86 1 times, resulting in a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 52 from 86 and we're left with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 52

Going ahead to step 3:
343 divided by 52 is 6 with a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 312 from 343, we get 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 52

Advancing to step 4:
316 divided by 52 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 166.0
Subtract 312 from 316 to get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 52

Let's proceed to step 5:
52 can be fit into 46 0 times, resulting in a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 1660.0
Subtract 0 from 46 to get 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 52

Advancing to step 6:
When dividing 465 by 52, we get 8 with a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 16608.0
Deduct 416 from 465 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
When dividing 490 by 52, we get 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 16608.9
The remainder is 22 after subtracting 468 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
The number 52 fits into 220 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 16608.94
Deduct 208 from 220 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.

Moving on to step 9:
When dividing 120 by 52, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 16608.942
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.

Step 10:
If we divide 160 by 52, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 16608.9423
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 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: 16608.9423
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.

Going ahead to step 12:
400 divided by 52 is 7 with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 16608.942307
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.

Going ahead to step 13:
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: 16608.9423076
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.

Advancing to step 14:
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: 16608.94230769
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.

After the division, we end up with 16608.94230769 and a remainder of 1.2e-08.
