42240429 divided by 144 
We want to figure out the number of times 42240429 can be divided by 144.

Let's proceed to step 1:
144 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 144

Going ahead to step 2:
42 divided by 144 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 144

Moving on to step 3:
When dividing 422 by 144, we get 2 with a remainder of 134.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 134 after subtracting 288 from 422.
Include the next digit (4) from the dividend after 134, then repeat: 1344 / 144

Advancing to step 4:
1344 divided by 144 is 9 with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 1296 from 1344 leaves us with 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 144

Moving on to step 5:
When dividing 480 by 144, we get 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 293.0
The remainder is 48 after subtracting 432 from 480.
Bring next digit (4) of the dividend behind the 48 and repeat the process: 484 / 144

Let's proceed to step 6:
The number 144 fits into 484 3 times, leaving a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 2933.0
If we take 432 away from 484, we end up with 52.
Grab the next digit (2) from the dividend, add it to 52, then carry on: 522 / 144

Moving on to step 7:
If we divide 522 by 144, we get 3 and a remainder of 90.
Write down 3 as next digit of the result. 
Result so far: 29333.0
Subtract 432 from 522 to get 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 144

Advancing to step 8:
If we divide 909 by 144, we get 6 and a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 293336.0
Subtracting 864 from 909 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
When dividing 450 by 144, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 293336.3
If we take 432 away from 450, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
180 divided by 144 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 293336.31
If we subtract 144 from 180, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
The number 144 fits into 360 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 293336.312
If we take 288 away from 360, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
When dividing 720 by 144, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 293336.3125
Subtracting 720 from 720 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
When dividing 0 by 144, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 293336.3125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 14:
When dividing 0 by 144, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 293336.3125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 293336.3125, and the remainder is 0.0.
