158159 ÷ 30 
We want to divide 158159 by 30.

Moving on to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 30

Advancing to step 2:
30 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 30

Moving on to step 3:
30 goes into 158 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 150 from 158 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 30

On to step 4:
If we divide 81 by 30, we get 2 and a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 60 from 81, we get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 30

Moving on to step 5:
When dividing 215 by 30, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 527.0
If we take 210 away from 215, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 30

Let's proceed to step 6:
The number 30 fits into 59 1 times, leaving a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 5271.0
Subtract 30 from 59 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
30 goes into 290 9 times with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 5271.9
Deduct 270 from 290 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 5271.96
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 5271.966
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 5271.966 with a remainder of 0.002.
