We look at the division of 687068 by 52 
The aim is to understand the frequency of 52 in 687068.

Step 1:
When dividing 6 by 52, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 52

Moving on to step 2:
68 divided by 52 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 52 from 68 leaves us with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 52

Step 3:
The number 52 fits into 167 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 156 from 167 and we're left with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 52

Step 4:
52 goes into 110 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
If we take 104 away from 110, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 52

Step 5:
When dividing 66 by 52, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1321.0
Subtracting 52 from 66 leaves us with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 52

Step 6:
52 can be fit into 148 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 13212.0
If we subtract 104 from 148, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
52 can be fit into 440 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 13212.8
Subtract 416 from 440 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
52 can be fit into 240 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 13212.84
The remainder is 32 after subtracting 208 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
320 divided by 52 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 13212.846
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
The number 52 fits into 80 1 times, leaving a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 13212.8461
If we subtract 52 from 80, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
If we divide 280 by 52, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 13212.84615
If we subtract 260 from 280, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
52 can be fit into 200 3 times, resulting in a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 13212.846153
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
The number 52 fits into 440 8 times, leaving a remainder of 24.
The next digit of our result is 8. 
Result so far: 13212.8461538
Subtract 416 from 440 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
If we divide 240 by 52, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 13212.84615384
If we take 208 away from 240, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 13212.84615384 with a remainder of 3.2e-08.
