158393 divided by 53 
The aim is to understand the frequency of 53 in 158393.

Let's proceed to step 1:
1 divided by 53 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 53

Step 2:
53 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 53

On to step 3:
53 goes into 158 2 times with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 106 from 158 to get 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 53

On to step 4:
If we divide 523 by 53, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtract 477 from 523 to get 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 53

Let's proceed to step 5:
469 divided by 53 is 8 with a remainder of 45.
The next digit of our result is 8. 
Result so far: 298.0
If we subtract 424 from 469, we get 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 53

Step 6:
53 goes into 453 8 times with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 2988.0
Deduct 424 from 453 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
The number 53 fits into 290 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2988.5
If we take 265 away from 290, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
53 can be fit into 250 4 times, resulting in a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 2988.54
If we take 212 away from 250, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
53 goes into 380 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 2988.547
Subtracting 371 from 380 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
53 can be fit into 90 1 times, resulting in a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 2988.5471
If we take 53 away from 90, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 11:
370 divided by 53 is 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 2988.54716
Deduct 318 from 370 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
520 divided by 53 is 9 with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 2988.547169
Deduct 477 from 520 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
53 can be fit into 430 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 2988.5471698
The remainder is 6 after subtracting 424 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
When dividing 60 by 53, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 2988.54716981
The remainder is 7 after subtracting 53 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 2988.54716981 with a remaining 7e-09.
