159889 ÷ 3 
We want to divide 159889 by 3.

Moving on to step 1:
If we divide 1 by 3, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Let's proceed to step 2:
If we divide 15 by 3, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 15 from 15, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 3

Step 3:
When dividing 9 by 3, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we take 9 away from 9, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Let's proceed to step 4:
3 goes into 8 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 532.0
The remainder is 2 after subtracting 6 from 8.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

On to step 5:
28 divided by 3 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 5329.0
If we subtract 27 from 28, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

Step 6:
When dividing 19 by 3, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 53296.0
If we take 18 away from 19, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 53296.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 53296.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 53296.33 with a remainder of 0.001.
