We look at the division of 688094 by 52 
The aim is to understand the frequency of 52 in 688094.

Step 1:
If we divide 6 by 52, we get 0 and 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.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 52

Step 2:
The number 52 fits into 68 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 16 after subtracting 52 from 68.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 52

Advancing to step 3:
If we divide 168 by 52, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 156 from 168 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 52

Let's proceed to step 4:
If we divide 120 by 52, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
If we take 104 away from 120, we end up with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 52

Step 5:
52 goes into 169 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 1323.0
The remainder is 13 after subtracting 156 from 169.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 52

Let's proceed to step 6:
If we divide 134 by 52, we get 2 and a remainder of 30.
The next digit of our result is 2. 
Result so far: 13232.0
Deduct 104 from 134 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.

Going ahead to step 7:
The number 52 fits into 300 5 times, leaving a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 13232.5
Deduct 260 from 300 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.

Let's proceed to step 8:
400 divided by 52 is 7 with a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 13232.57
Subtracting 364 from 400 leaves us 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 9:
52 can be fit into 360 6 times, resulting in a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 13232.576
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.

On to step 10:
The number 52 fits into 480 9 times, leaving a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 13232.5769
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.

Step 11:
52 goes into 120 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 13232.57692
Subtract 104 from 120 to 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.

Let's proceed to step 12:
The number 52 fits into 160 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 13232.576923
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
When dividing 40 by 52, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 13232.576923
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 14:
The number 52 fits into 400 7 times, leaving a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 13232.57692307
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.

The final outcome is 13232.57692307, with a leftover of 3.6e-08.
