149331 ÷ 78 
Our goal is to divide 149331 by 78.

Advancing to step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 78

Advancing to 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
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 78

Moving on to step 3:
149 divided by 78 is 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 71 after subtracting 78 from 149.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 78

Advancing to step 4:
If we divide 713 by 78, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 11 after subtracting 702 from 713.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 78

Let's proceed to step 5:
The number 78 fits into 113 1 times, leaving a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
If we subtract 78 from 113, we get 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 78

Moving on to step 6:
If we divide 351 by 78, we get 4 and a remainder of 39.
The next digit of our result is 4. 
Result so far: 1914.0
Subtracting 312 from 351 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
78 goes into 390 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1914.5
Subtract 390 from 390 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.

Step 8:
0 divided by 78 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1914.5
If we take 0 away from 0, 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.

Moving on to step 9:
The number 78 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1914.5
Subtracting 0 from 0 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.

The final outcome is 1914.5, with a leftover of 0.0.
