18204 ÷ 87 
We want to figure out the number of times 18204 can be divided by 87.

On to step 1:
87 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 87

Let's proceed to step 2:
18 divided by 87 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 87

Going ahead to step 3:
When dividing 182 by 87, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we take 174 away from 182, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 87

Moving on to step 4:
If we divide 80 by 87, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 80 to get 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 87

On to step 5:
If we divide 804 by 87, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 209.0
Subtracting 783 from 804 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 6:
The number 87 fits into 210 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 209.2
Deduct 174 from 210 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
When dividing 360 by 87, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 209.24
Subtracting 348 from 360 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
The number 87 fits into 120 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 209.241
The remainder is 33 after subtracting 87 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
When dividing 330 by 87, we get 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 209.2413
Subtract 261 from 330 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 10:
When dividing 690 by 87, we get 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 209.24137
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 11:
87 goes into 810 9 times with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.241379
Subtracting 783 from 810 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
270 divided by 87 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 209.2413793
If we subtract 261 from 270, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
87 goes into 90 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 209.24137931
If we subtract 87 from 90, 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.

After the division, we end up with 209.24137931 and a remainder of 3e-09.
