Let's divide 144573 by 78
We're looking to find how many times 78 goes into 144573.

Moving on to step 1:
1 divided by 78 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 78

Step 2:
The number 78 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 78

Going ahead to step 3:
144 divided by 78 is 1 with a remainder of 66.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 66 after subtracting 78 from 144.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 78

Going ahead to step 4:
The number 78 fits into 665 8 times, leaving a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 624 from 665 to get 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 78

Step 5:
If we divide 417 by 78, we get 5 and a remainder of 27.
The next digit of our result is 5. 
Result so far: 185.0
If we subtract 390 from 417, we get 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 78

Let's proceed to step 6:
78 goes into 273 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 1853.0
Subtract 234 from 273 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
If we divide 390 by 78, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 1853.5
If we take 390 away from 390, we end up 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.

Going ahead to step 8:
0 divided by 78 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1853.5
Subtract 0 from 0 to 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.

Going ahead to step 9:
The number 78 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1853.5
Subtract 0 from 0 to 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 1853.5 with a remainder of 0.0.
