135720 ÷ 87 
We want to figure out the number of times 135720 can be divided by 87.

Advancing to step 1:
When dividing 1 by 87, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 87

Going ahead to step 2:
13 divided by 87 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 87

On to step 3:
The number 87 fits into 135 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 48 after subtracting 87 from 135.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 87

Let's proceed to step 4:
When dividing 487 by 87, we get 5 with a remainder of 52.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 435 from 487 and we're left with 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 87

Going ahead to step 5:
522 divided by 87 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
Subtracting 522 from 522 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 87

On to step 6:
If we divide 0 by 87, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1560.0
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.

On to step 7:
87 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1560.0
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:
87 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1560.0
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.

Our division results in 1560.0 with a remaining 0.0.
