We look at the division of 144942 by 53 
The aim is to understand the frequency of 53 in 144942.

Let's proceed to step 1:
53 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 53

On to step 2:
If we divide 14 by 53, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 53

Going ahead to step 3:
If we divide 144 by 53, we get 2 and a remainder of 38.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 38 after subtracting 106 from 144.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 53

Let's proceed to step 4:
389 divided by 53 is 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 371 from 389 to get 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 53

Step 5:
184 divided by 53 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
The remainder is 25 after subtracting 159 from 184.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 53

Moving on to step 6:
When dividing 252 by 53, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 2734.0
Deduct 212 from 252 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
If we divide 400 by 53, we get 7 and a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 2734.7
Subtracting 371 from 400 leaves us 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.

Step 8:
290 divided by 53 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2734.75
Subtract 265 from 290 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
When dividing 250 by 53, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 2734.754
If we subtract 212 from 250, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
380 divided by 53 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 2734.7547
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.

On to step 11:
53 goes into 90 1 times with a remainder of 37.
The next digit of our result is 1. 
Result so far: 2734.75471
If we subtract 53 from 90, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
If we divide 370 by 53, we get 6 and a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 2734.754716
The remainder is 52 after subtracting 318 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
520 divided by 53 is 9 with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 2734.7547169
If we take 477 away from 520, we end up 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.

Step 14:
If we divide 430 by 53, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 2734.75471698
Deduct 424 from 430 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 2734.75471698 with a remaining 6e-09.
