We look at the division of 20155659 by 144 
The aim is to understand the frequency of 144 in 20155659.

Step 1:
The number 144 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 144

Going ahead to step 2:
144 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 144

Let's proceed to step 3:
144 can be fit into 201 1 times, resulting in a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 144 from 201 and we're left with 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 144

Let's proceed to step 4:
When dividing 575 by 144, we get 3 with a remainder of 143.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 432 from 575 and we're left with 143.
Bring next digit (5) of the dividend behind the 143 and repeat the process: 1435 / 144

Let's proceed to step 5:
1435 divided by 144 is 9 with a remainder of 139.
Use 9 as the next digit of our solution. 
Result so far: 139.0
The remainder is 139 after subtracting 1296 from 1435.
Include the next digit (6) from the dividend after 139, then repeat: 1396 / 144

Advancing to step 6:
144 goes into 1396 9 times with a remainder of 100.
The number 9 becomes the next digit in our result. 
Result so far: 1399.0
Subtracting 1296 from 1396 leaves us with 100.
Take the next digit (5) from the dividend and append it to 100, then repeat: 1005 / 144

Going ahead to step 7:
The number 144 fits into 1005 6 times, leaving a remainder of 141.
Write down 6 as next digit of the result. 
Result so far: 13996.0
If we take 864 away from 1005, we end up with 141.
Fetch the next digit (9) from the dividend, attach it to 141 and continue: 1419 / 144

Moving on to step 8:
144 can be fit into 1419 9 times, resulting in a remainder of 123.
Use 9 as the next digit of our solution. 
Result so far: 139969.0
Subtract 1296 from 1419 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
When dividing 1230 by 144, we get 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 139969.8
Subtracting 1152 from 1230 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
If we divide 780 by 144, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 139969.85
If we take 720 away from 780, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
The number 144 fits into 600 4 times, leaving a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 139969.854
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
The number 144 fits into 240 1 times, leaving a remainder of 96.
Record the quotient 1 as the next digit in the result. 
Result so far: 139969.8541
Subtract 144 from 240 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
The number 144 fits into 960 6 times, leaving a remainder of 96.
The next digit of our result is 6. 
Result so far: 139969.85416
Subtract 864 from 960 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 14:
When dividing 960 by 144, we get 6 with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 139969.854166
If we subtract 864 from 960, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

In conclusion, the division gives 139969.854166 with a balance of 9.6e-06.
