We look at the division of 647974 by 53 
The aim is to understand the frequency of 53 in 647974.

Going ahead to step 1:
When dividing 6 by 53, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 53

Moving on to step 2:
53 can be fit into 64 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 11 after subtracting 53 from 64.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 53

Advancing to step 3:
When dividing 117 by 53, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 106 from 117 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 53

Advancing to step 4:
53 can be fit into 119 2 times, resulting in a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Subtracting 106 from 119 leaves us with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 53

Step 5:
If we divide 137 by 53, we get 2 and a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 1222.0
If we subtract 106 from 137, we get 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 53

Advancing to step 6:
If we divide 314 by 53, we get 5 and a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 12225.0
Subtracting 265 from 314 leaves us 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.

On to step 7:
If we divide 490 by 53, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 12225.9
The remainder is 13 after subtracting 477 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
When dividing 130 by 53, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 12225.92
If we subtract 106 from 130, we 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 9:
240 divided by 53 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 12225.924
Subtract 212 from 240 to 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.

Moving on to step 10:
If we divide 280 by 53, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 12225.9245
If we subtract 265 from 280, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
When dividing 150 by 53, we get 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 12225.92452
Deduct 106 from 150 and we're left 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.

On to step 12:
If we divide 440 by 53, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 12225.924528
If we subtract 424 from 440, 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.

Going ahead to step 13:
160 divided by 53 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 12225.9245283
If we subtract 159 from 160, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
If we divide 10 by 53, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12225.9245283
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 12225.9245283 with a remainder of 1e-08.
