2379561 ÷ 144 
The aim is to understand the frequency of 144 in 2379561.

Step 1:
If we divide 2 by 144, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 144

Advancing to step 2:
When dividing 23 by 144, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 144

Going ahead to step 3:
When dividing 237 by 144, we get 1 with a remainder of 93.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 144 from 237 leaves us with 93.
Include the next digit (9) from the dividend after 93, then repeat: 939 / 144

Going ahead to step 4:
144 can be fit into 939 6 times, resulting in a remainder of 75.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 75 after subtracting 864 from 939.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 144

Moving on to step 5:
144 goes into 755 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
The remainder is 35 after subtracting 720 from 755.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 144

Going ahead to step 6:
When dividing 356 by 144, we get 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 1652.0
Subtracting 288 from 356 leaves us with 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 144

Step 7:
681 divided by 144 is 4 with a remainder of 105.
The next digit of our result is 4. 
Result so far: 16524.0
Subtracting 576 from 681 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 8:
144 goes into 1050 7 times with a remainder of 42.
The next digit of our result is 7. 
Result so far: 16524.7
The remainder is 42 after subtracting 1008 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
If we divide 420 by 144, we get 2 and a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 16524.72
The remainder is 132 after subtracting 288 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 10:
When dividing 1320 by 144, we get 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 16524.729
Deduct 1296 from 1320 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
When dividing 240 by 144, we get 1 with a remainder of 96.
The next digit of our result is 1. 
Result so far: 16524.7291
The remainder is 96 after subtracting 144 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 12:
144 can be fit into 960 6 times, resulting in a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 16524.72916
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.

Going ahead to step 13:
144 can be fit into 960 6 times, resulting in a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 16524.729166
The remainder is 96 after subtracting 864 from 960.
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 16524.729166 with a balance of 9.6e-06.
