642481 divided by 53 
The aim is to understand the frequency of 53 in 642481.

Moving on to step 1:
53 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 53

Moving on to step 2:
64 divided by 53 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 11 after subtracting 53 from 64.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 53

Let's proceed to step 3:
112 divided by 53 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 106 away from 112, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 53

Going ahead to step 4:
53 goes into 64 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 121.0
If we take 53 away from 64, we end up with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 53

Step 5:
53 can be fit into 118 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 1212.0
If we take 106 away from 118, we end up with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 53

Moving on to step 6:
53 goes into 121 2 times with a remainder of 15.
The next digit of our result is 2. 
Result so far: 12122.0
Subtracting 106 from 121 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
53 goes into 150 2 times with a remainder of 44.
The next digit of our result is 2. 
Result so far: 12122.2
If we take 106 away from 150, we end up 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.

Advancing to step 8:
440 divided by 53 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 12122.28
Deduct 424 from 440 and we're left 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.

On to step 9:
53 goes into 160 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 12122.283
If we take 159 away from 160, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
If we divide 10 by 53, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12122.283
Subtracting 0 from 10 leaves us 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.

Moving on to step 11:
53 goes into 100 1 times with a remainder of 47.
The next digit of our result is 1. 
Result so far: 12122.28301
Deduct 53 from 100 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
When dividing 470 by 53, we get 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 12122.283018
Subtracting 424 from 470 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
The number 53 fits into 460 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 12122.2830188
If we take 424 away from 460, 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.

The final result is 12122.2830188 with a remainder of 3.6e-07.
