Let's divide 138650 by 3
We're looking to find how many times 3 goes into 138650.

Going ahead to step 1:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 3

Moving on to step 2:
The number 3 fits into 13 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 12 from 13 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Moving on to step 3:
3 can be fit into 18 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 46.0
The remainder is 0 after subtracting 18 from 18.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 3

Going ahead to step 4:
6 divided by 3 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 462.0
If we subtract 6 from 6, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

On to step 5:
3 goes into 5 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 4621.0
Deduct 3 from 5 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 3

Going ahead to step 6:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 46216.0
If we subtract 18 from 20, we 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.

Let's proceed to step 7:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 46216.6
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.

Step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 46216.66
If we subtract 18 from 20, we 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.

The quotient of the division is 46216.66, and the remainder is 0.002.
