We're dividing 135571 by 5 
We want to figure out the number of times 135571 can be divided by 5.

On to step 1:
If we divide 1 by 5, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 5

Moving on to step 2:
The number 5 fits into 13 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 10 from 13 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 5

Going ahead to step 3:
5 goes into 35 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 35 from 35 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 5

Let's proceed to step 4:
When dividing 5 by 5, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 271.0
The remainder is 0 after subtracting 5 from 5.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 5

Step 5:
The number 5 fits into 7 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 2711.0
The remainder is 2 after subtracting 5 from 7.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 5

Advancing to step 6:
If we divide 21 by 5, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 27114.0
If we take 20 away from 21, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 5 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 27114.2
If we subtract 10 from 10, 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.

On to step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 27114.2
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.

Step 9:
0 divided by 5 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27114.2
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.

Our division results in 27114.2 with a remaining 0.0.
