We're dividing 18486395 by 87 
We want to figure out the number of times 18486395 can be divided by 87.

On to step 1:
1 divided by 87 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 87

On to step 2:
If we divide 18 by 87, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 87

Let's proceed to step 3:
184 divided by 87 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 174 from 184 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 87

Step 4:
If we divide 108 by 87, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 87 from 108 to get 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 87

Going ahead to step 5:
When dividing 216 by 87, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
The remainder is 42 after subtracting 174 from 216.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 87

Advancing to step 6:
87 goes into 423 4 times with a remainder of 75.
The next digit of our result is 4. 
Result so far: 2124.0
Subtract 348 from 423 to get 75.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 87

Step 7:
87 can be fit into 759 8 times, resulting in a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 21248.0
Deduct 696 from 759 and we're left with 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 87

Let's proceed to step 8:
635 divided by 87 is 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 212487.0
If we subtract 609 from 635, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
If we divide 260 by 87, we get 2 and a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 212487.2
If we subtract 174 from 260, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 10:
87 goes into 860 9 times with a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 212487.29
If we take 783 away from 860, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 11:
87 goes into 770 8 times with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 212487.298
Subtract 696 from 770 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 12:
When dividing 740 by 87, we get 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 212487.2988
Subtracting 696 from 740 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 212487.2988 and a remainder of 0.00044.
