Let's divide 104535 by 87
We're looking to find how many times 87 goes into 104535.

On to step 1:
1 divided by 87 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 87

On to step 2:
When dividing 10 by 87, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 87

Let's proceed to step 3:
87 goes into 104 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 17 after subtracting 87 from 104.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 87

Advancing to step 4:
87 goes into 175 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 174 from 175, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 87

Going ahead to step 5:
When dividing 13 by 87, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 120.0
Subtract 0 from 13 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 87

Going ahead to step 6:
If we divide 135 by 87, we get 1 and a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1201.0
Subtracting 87 from 135 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
The number 87 fits into 480 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 1201.5
Subtracting 435 from 480 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
87 goes into 450 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1201.55
The remainder is 15 after subtracting 435 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 1201.55, and the remainder is 0.015.
