135549 ÷ 87 
We're looking to find how many times 87 goes into 135549.

Let's proceed to step 1:
87 goes into 1 0 times with 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 / 87

Advancing to step 2:
87 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 87

Going ahead to step 3:
87 can be fit into 135 1 times, resulting in a remainder of 48.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 87 from 135 to get 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 87

Moving on to step 4:
485 divided by 87 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 435 from 485, we get 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 87

On to step 5:
If we divide 504 by 87, we get 5 and a remainder of 69.
The next digit of our result is 5. 
Result so far: 155.0
If we subtract 435 from 504, we get 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 87

Advancing to step 6:
The number 87 fits into 699 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 1558.0
If we subtract 696 from 699, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 87 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 1558.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 87 is 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 1558.03
Deduct 261 from 300 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 9:
The number 87 fits into 390 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 1558.034
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
The number 87 fits into 420 4 times, leaving a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 1558.0344
Deduct 348 from 420 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 1558.0344 and a remainder of 0.00072.
