30260904 ÷ 144 
Let's see how many times 144 fits into 30260904.

On to step 1:
If we divide 3 by 144, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 144

Step 2:
If we divide 30 by 144, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 144

Step 3:
144 goes into 302 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 288 from 302 and we're left with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 144

Advancing to step 4:
146 divided by 144 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 144 from 146 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 144

Let's proceed to step 5:
20 divided by 144 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 210.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 144

On to step 6:
When dividing 209 by 144, we get 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 2101.0
If we take 144 away from 209, we end up with 65.
Include the next digit (0) from the dividend after 65, then repeat: 650 / 144

Let's proceed to step 7:
650 divided by 144 is 4 with a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 21014.0
If we subtract 576 from 650, we get 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 144

Moving on to step 8:
144 goes into 744 5 times with a remainder of 24.
The next digit of our result is 5. 
Result so far: 210145.0
The remainder is 24 after subtracting 720 from 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 144 is 1 with a remainder of 96.
Put 1 as the next digit of the answer. 
Result so far: 210145.1
If we take 144 away from 240, we end up with 96.
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 10:
The number 144 fits into 960 6 times, leaving a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 210145.16
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.

Moving on to step 11:
When dividing 960 by 144, we get 6 with a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 210145.166
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.

Our division results in 210145.166 with a remaining 0.0096.
