18809554 divided by 144 
The aim is to understand the frequency of 144 in 18809554.

Going ahead to step 1:
144 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 144

On to step 2:
When dividing 18 by 144, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 144

Moving on to step 3:
When dividing 188 by 144, we get 1 with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 144 from 188 to get 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 144

Moving on to step 4:
144 can be fit into 440 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 432 away from 440, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 144

Let's proceed to step 5:
When dividing 89 by 144, we get 0 with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we take 0 away from 89, we end up with 89.
Include the next digit (5) from the dividend after 89, then repeat: 895 / 144

Going ahead to step 6:
144 goes into 895 6 times with a remainder of 31.
The next digit of our result is 6. 
Result so far: 1306.0
The remainder is 31 after subtracting 864 from 895.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 144

On to step 7:
The number 144 fits into 315 2 times, leaving a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 13062.0
The remainder is 27 after subtracting 288 from 315.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 144

Going ahead to step 8:
274 divided by 144 is 1 with a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 130621.0
If we take 144 away from 274, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 9:
1300 divided by 144 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 130621.9
If we subtract 1296 from 1300, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
144 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 130621.9
Deduct 0 from 40 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.

On to step 11:
If we divide 400 by 144, we get 2 and a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 130621.902
Subtract 288 from 400 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
144 can be fit into 1120 7 times, resulting in a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 130621.9027
Subtract 1008 from 1120 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 13:
1120 divided by 144 is 7 with a remainder of 112.
Record the quotient 7 as the next digit in the result. 
Result so far: 130621.90277
Subtracting 1008 from 1120 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 130621.90277, with a leftover of 0.000112.
