159305 ÷ 3 
We want to divide 159305 by 3.

Going ahead to step 1:
1 divided by 3 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Let's proceed to step 2:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 0 after subtracting 15 from 15.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Moving on to step 3:
When dividing 9 by 3, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 53.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Going ahead to step 4:
3 goes into 3 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 531.0
If we take 3 away from 3, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

On to step 5:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5310.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Advancing to step 6:
If we divide 5 by 3, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 53101.0
If we take 3 away from 5, 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.

Step 7:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 53101.6
Deduct 18 from 20 and we're left 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.

Moving on to step 8:
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: 53101.66
Deduct 18 from 20 and we're left 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 53101.66 with a remaining 0.002.
