Let's divide 159985 by 5
We're looking to find how many times 5 goes into 159985.

Step 1:
The number 5 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 5

Step 2:
5 can be fit into 15 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 15 away from 15, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 5

Moving on to step 3:
9 divided by 5 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 5 from 9 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 5

Moving on to step 4:
If we divide 49 by 5, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 319.0
If we take 45 away from 49, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 5

Advancing to step 5:
5 can be fit into 48 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 3199.0
If we subtract 45 from 48, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 5

Step 6:
The number 5 fits into 35 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 31997.0
Subtracting 35 from 35 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31997.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31997.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 31997.0, with a leftover of 0.0.
