We look at the division of 159843 by 53 
The aim is to understand the frequency of 53 in 159843.

Step 1:
1 divided by 53 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 53

Step 2:
15 divided by 53 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 53

Going ahead to step 3:
If we divide 159 by 53, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 159 from 159 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 53

Moving on to step 4:
When dividing 8 by 53, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 53

Going ahead to step 5:
When dividing 84 by 53, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 301.0
If we take 53 away from 84, we end up with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 53

Step 6:
When dividing 313 by 53, we get 5 with a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 3015.0
The remainder is 48 after subtracting 265 from 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
The number 53 fits into 480 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 3015.9
If we take 477 away from 480, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
30 divided by 53 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3015.9
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
When dividing 300 by 53, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3015.905
Subtracting 265 from 300 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
350 divided by 53 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 3015.9056
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.

Going ahead to step 11:
The number 53 fits into 320 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 3015.90566
If we subtract 318 from 320, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 3015.90566 with a balance of 2e-06.
