We're dividing 138857 by 5 
We want to figure out the number of times 138857 can be divided by 5.

Moving on to step 1:
When dividing 1 by 5, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 5

Step 2:
The number 5 fits into 13 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 10 away from 13, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 5

Going ahead to step 3:
The number 5 fits into 38 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtracting 35 from 38 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 5

Advancing to step 4:
When dividing 38 by 5, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 277.0
Subtract 35 from 38 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 5

Let's proceed to step 5:
The number 5 fits into 35 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 2777.0
If we take 35 away from 35, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 5

Step 6:
If we divide 7 by 5, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 27771.0
Subtract 5 from 7 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
5 goes into 20 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 27771.4
Subtract 20 from 20 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.

Step 8:
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: 27771.4
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.

Advancing to step 9:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27771.4
Subtracting 0 from 0 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.

After the division, we end up with 27771.4 and a remainder of 0.0.
