150280 ÷ 78 
Our goal is to divide 150280 by 78.

Step 1:
78 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 78

Going ahead to step 2:
The number 78 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 78

Going ahead to step 3:
If we divide 150 by 78, we get 1 and a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 78 from 150 leaves us with 72.
Include the next digit (2) from the dividend after 72, then repeat: 722 / 78

Let's proceed to step 4:
78 goes into 722 9 times with a remainder of 20.
The next digit of our result is 9. 
Result so far: 19.0
If we take 702 away from 722, we end up with 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 78

Let's proceed to step 5:
The number 78 fits into 208 2 times, leaving a remainder of 52.
The next digit of our result is 2. 
Result so far: 192.0
Subtract 156 from 208 to get 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 78

On to step 6:
520 divided by 78 is 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 1926.0
Deduct 468 from 520 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
78 can be fit into 520 6 times, resulting in a remainder of 52.
The next digit of our result is 6. 
Result so far: 1926.6
Deduct 468 from 520 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
When dividing 520 by 78, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 1926.66
If we subtract 468 from 520, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 1926.66 and a remainder of 0.052.
