139850 ÷ 3 
We're looking to find how many times 3 goes into 139850.

Let's proceed to step 1:
When dividing 1 by 3, we get 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.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

Moving on to step 2:
3 goes into 13 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 1 after subtracting 12 from 13.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

Moving on to step 3:
If we divide 19 by 3, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
The remainder is 1 after subtracting 18 from 19.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Moving on to 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: 466.0
Subtract 18 from 18 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

Let's proceed to step 5:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 4661.0
Subtracting 3 from 5 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Going ahead to step 6:
If we divide 20 by 3, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 46616.0
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.

Let's proceed to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 46616.6
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.

Going ahead to step 8:
3 goes into 20 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 46616.66
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.

The quotient of the division is 46616.66, and the remainder is 0.002.
