443910 ÷ 3 
We want to divide 443910 by 3.

Let's proceed to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 3 away from 4, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Moving on to step 2:
3 goes into 14 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 12 from 14 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Advancing to step 3:
If we divide 23 by 3, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 147.0
If we subtract 21 from 23, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

On to step 4:
3 goes into 29 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1479.0
The remainder is 2 after subtracting 27 from 29.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

On to step 5:
3 goes into 21 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 14797.0
Subtract 21 from 21 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Step 6:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 147970.0
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.

Step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 147970.0
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.

Step 8:
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: 147970.0
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.

Our division results in 147970.0 with a remaining 0.0.
