90939 ÷ 5 
We're looking to find how many times 5 goes into 90939.

Let's proceed to step 1:
When dividing 9 by 5, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 5 from 9 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 5

Advancing to step 2:
If we divide 40 by 5, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 40 from 40 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 5

Moving on to step 3:
When dividing 9 by 5, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 181.0
If we take 5 away from 9, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 5

Moving on to step 4:
The number 5 fits into 43 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 1818.0
If we take 40 away from 43, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 5

On to step 5:
39 divided by 5 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 18187.0
Subtracting 35 from 39 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 6:
5 can be fit into 40 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 18187.8
If we take 40 away from 40, 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.

Going ahead to step 7:
0 divided by 5 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18187.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 5 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18187.8
If we subtract 0 from 0, we get 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 18187.8, with a leftover of 0.0.
