20057 ÷ 5 
We want to figure out the number of times 20057 can be divided by 5.

On to step 1:
When dividing 2 by 5, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 5

On to step 2:
If we divide 20 by 5, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 20 from 20 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 5

Step 3:
If we divide 0 by 5, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 0, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 5

Let's proceed to step 4:
5 divided by 5 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 401.0
Subtract 5 from 5 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 5

Moving on to step 5:
If we divide 7 by 5, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 4011.0
Subtracting 5 from 7 leaves us 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.

Let's proceed to step 6:
20 divided by 5 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4011.4
Subtracting 20 from 20 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.

Advancing to step 7:
0 divided by 5 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4011.4
Subtract 0 from 0 to 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.

Moving on to step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4011.4
The remainder is 0 after subtracting 0 from 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 result is 4011.4 with a remainder of 0.0.
