148236 ÷ 3 
We want to divide 148236 by 3.

On to step 1:
1 divided by 3 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Going ahead to step 2:
The number 3 fits into 14 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 12 from 14 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

Step 3:
If we divide 28 by 3, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we take 27 away from 28, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 3

On to step 4:
The number 3 fits into 12 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 494.0
Deduct 12 from 12 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

On to step 5:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 4941.0
The remainder is 0 after subtracting 3 from 3.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 3

Step 6:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 49412.0
If we subtract 6 from 6, we 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.

Moving on to step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49412.0
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.

Advancing to step 8:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 49412.0
If we subtract 0 from 0, we 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.

After the division, we end up with 49412.0 and a remainder of 0.0.
