We're dividing 124820 by 3 
We want to divide 124820 by 3.

Advancing to step 1:
1 divided by 3 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

On to step 2:
3 can be fit into 12 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
If we take 12 away from 12, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Moving on to step 3:
If we divide 4 by 3, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Deduct 3 from 4 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Step 4:
If we divide 18 by 3, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
Subtract 18 from 18 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 3

Step 5:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 4160.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 3

On to step 6:
When dividing 20 by 3, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 41606.0
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 41606.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 41606.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 41606.66 with a remaining 0.002.
