Let's divide 144063 by 52
The aim is to understand the frequency of 52 in 144063.

On to step 1:
1 divided by 52 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.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 52

Advancing to step 2:
When dividing 14 by 52, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 52

Going ahead to step 3:
The number 52 fits into 144 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 104 from 144, we get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 52

Let's proceed to step 4:
If we divide 400 by 52, we get 7 and a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 36 after subtracting 364 from 400.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 52

Moving on to step 5:
The number 52 fits into 366 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 277.0
Deduct 364 from 366 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 52

Moving on to step 6:
52 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 2770.0
The remainder is 23 after subtracting 0 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
52 goes into 230 4 times with a remainder of 22.
The next digit of our result is 4. 
Result so far: 2770.4
If we subtract 208 from 230, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
When dividing 220 by 52, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 2770.44
Subtract 208 from 220 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 2770.44 and a remainder of 0.012.
