Our goal is to divide 90387324 by 144.

Moving on to step 1:
9 divided by 144 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 144

Moving on to step 2:
The number 144 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (3) of the dividend behind the 90 and repeat the process: 903 / 144

On to step 3:
903 divided by 144 is 6 with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 864 from 903, we get 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 144

On to step 4:
398 divided by 144 is 2 with a remainder of 110.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
The remainder is 110 after subtracting 288 from 398.
Fetch the next digit (7) from the dividend, attach it to 110 and continue: 1107 / 144

Advancing to step 5:
144 can be fit into 1107 7 times, resulting in a remainder of 99.
Put 7 as the next digit of the answer. 
Result so far: 627.0
Subtracting 1008 from 1107 leaves us with 99.
Include the next digit (3) from the dividend after 99, then repeat: 993 / 144

On to step 6:
When dividing 993 by 144, we get 6 with a remainder of 129.
The number 6 becomes the next digit in our result. 
Result so far: 6276.0
Deduct 864 from 993 and we're left with 129.
Include the next digit (2) from the dividend after 129, then repeat: 1292 / 144

Advancing to step 7:
144 can be fit into 1292 8 times, resulting in a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 62768.0
The remainder is 140 after subtracting 1152 from 1292.
Grab the next digit (4) from the dividend, add it to 140, then carry on: 1404 / 144

Advancing to step 8:
144 goes into 1404 9 times with a remainder of 108.
The number 9 becomes the next digit in our result. 
Result so far: 627689.0
If we subtract 1296 from 1404, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 9:
144 goes into 1080 7 times with a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 627689.7
If we take 1008 away from 1080, 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 10:
144 goes into 720 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 627689.75
The remainder is 0 after subtracting 720 from 720.
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 11:
144 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 627689.75
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.

Advancing to step 12:
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: 627689.75
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 final result is 627689.75 with a remainder of 0.0.
