Let's divide 637939 by 53
The aim is to understand the frequency of 53 in 637939.

Going ahead 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
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 53

Going ahead to step 2:
63 divided by 53 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 53 from 63 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 53

Going ahead to step 3:
When dividing 107 by 53, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 106 from 107, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 53

On to step 4:
53 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 53

Moving on to step 5:
53 goes into 193 3 times with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 1203.0
If we take 159 away from 193, we end up with 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 53

Moving on to step 6:
If we divide 349 by 53, we get 6 and a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 12036.0
If we subtract 318 from 349, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
53 goes into 310 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 12036.5
Subtracting 265 from 310 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
450 divided by 53 is 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 12036.58
The remainder is 26 after subtracting 424 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
If we divide 260 by 53, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 12036.584
If we take 212 away from 260, 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:
480 divided by 53 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 12036.5849
If we subtract 477 from 480, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
When dividing 30 by 53, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 12036.5849
Subtracting 0 from 30 leaves us 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.

Step 12:
When dividing 300 by 53, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 12036.584905
If we subtract 265 from 300, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
350 divided by 53 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 12036.5849056
If we take 318 away from 350, 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.

Step 14:
320 divided by 53 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 12036.58490566
Subtracting 318 from 320 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 12036.58490566 and a remainder of 2e-09.
