145944 ÷ 3 
Let's see how many times 3 fits into 145944.

On to step 1:
3 goes into 1 0 times 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.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Advancing to step 2:
14 divided by 3 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 4.0
If we take 12 away from 14, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Step 3:
When dividing 25 by 3, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 24 from 25 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

Advancing to step 4:
19 divided by 3 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 486.0
Subtracting 18 from 19 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Moving on to step 5:
When dividing 14 by 3, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4864.0
The remainder is 2 after subtracting 12 from 14.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Let's proceed to step 6:
The number 3 fits into 24 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 48648.0
The remainder is 0 after subtracting 24 from 24.
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 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48648.0
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 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48648.0
The remainder is 0 after subtracting 0 from 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 48648.0, and the remainder is 0.0.
