72060989 ÷ 144 
We want to divide 72060989 by 144.

On to step 1:
The number 144 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 144

Advancing to step 2:
144 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 144

Moving on to step 3:
The number 144 fits into 720 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 720 from 720 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 144

Step 4:
144 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 6, we get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 144

Moving on to step 5:
144 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 500.0
The remainder is 60 after subtracting 0 from 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 144

Let's proceed to step 6:
144 goes into 609 4 times with a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 5004.0
If we subtract 576 from 609, we get 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 144

Going ahead to step 7:
338 divided by 144 is 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 50042.0
Subtracting 288 from 338 leaves us with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 144

On to step 8:
If we divide 509 by 144, we get 3 and a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 500423.0
If we take 432 away from 509, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 9:
When dividing 770 by 144, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 500423.5
Subtracting 720 from 770 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
When dividing 500 by 144, we get 3 with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 500423.53
Deduct 432 from 500 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
The number 144 fits into 680 4 times, leaving a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 500423.534
The remainder is 104 after subtracting 576 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 12:
1040 divided by 144 is 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 500423.5347
Deduct 1008 from 1040 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
144 can be fit into 320 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 500423.53472
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
When dividing 320 by 144, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 500423.534722
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 500423.534722, and the remainder is 3.2e-06.
