We look at the division of 19857953 by 144 
The aim is to understand the frequency of 144 in 19857953.

On to step 1:
If we divide 1 by 144, we get 0 and 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 (9) of the dividend behind the 1 and repeat the process: 19 / 144

Going ahead to step 2:
The number 144 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 144

Moving on to step 3:
198 divided by 144 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 144 away from 198, we end up with 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 144

Step 4:
545 divided by 144 is 3 with a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 432 away from 545, we end up with 113.
Grab the next digit (7) from the dividend, add it to 113, then carry on: 1137 / 144

On to step 5:
If we divide 1137 by 144, we get 7 and a remainder of 129.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtracting 1008 from 1137 leaves us with 129.
Take the next digit (9) from the dividend and append it to 129, then repeat: 1299 / 144

On to step 6:
1299 divided by 144 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 1379.0
Subtract 1296 from 1299 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 144

Step 7:
When dividing 35 by 144, we get 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 13790.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 144

Moving on to step 8:
144 can be fit into 353 2 times, resulting in a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 137902.0
If we take 288 away from 353, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
When dividing 650 by 144, we get 4 with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 137902.4
The remainder is 74 after subtracting 576 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
144 can be fit into 740 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 137902.45
The remainder is 20 after subtracting 720 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 144, we get 1 with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 137902.451
Deduct 144 from 200 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
560 divided by 144 is 3 with a remainder of 128.
Put 3 as the next digit of the answer. 
Result so far: 137902.4513
Subtracting 432 from 560 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 13:
The number 144 fits into 1280 8 times, leaving a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 137902.45138
If we take 1152 away from 1280, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 14:
144 goes into 1280 8 times with a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 137902.451388
The remainder is 128 after subtracting 1152 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 137902.451388 with a remainder of 1.28e-05.
