We look at the division of 72435277 by 144 
We want to divide 72435277 by 144.

Advancing to step 1:
144 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 144

Moving on to step 2:
If we divide 72 by 144, we get 0 and a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 144

On to step 3:
When dividing 724 by 144, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 720 from 724 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 144

Step 4:
43 divided by 144 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 144

Step 5:
If we divide 435 by 144, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 503.0
The remainder is 3 after subtracting 432 from 435.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 144

Let's proceed to step 6:
When dividing 32 by 144, we get 0 with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 5030.0
Subtracting 0 from 32 leaves us with 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 144

Going ahead to step 7:
327 divided by 144 is 2 with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 50302.0
If we subtract 288 from 327, we get 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 144

Advancing to step 8:
144 goes into 397 2 times with a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 503022.0
The remainder is 109 after subtracting 288 from 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 9:
If we divide 1090 by 144, we get 7 and a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 503022.7
Subtracting 1008 from 1090 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
If we divide 820 by 144, we get 5 and a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 503022.75
Subtract 720 from 820 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
144 can be fit into 1000 6 times, resulting in a remainder of 136.
The number 6 becomes the next digit in our result. 
Result so far: 503022.756
Subtract 864 from 1000 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 12:
The number 144 fits into 1360 9 times, leaving a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 503022.7569
Subtracting 1296 from 1360 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
When dividing 640 by 144, we get 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 503022.75694
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
144 can be fit into 640 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 503022.756944
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 503022.756944, with a leftover of 6.4e-06.
