We're dividing 87506 by 18 
We want to figure out the number of times 87506 can be divided by 18.

Step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 18

On to step 2:
87 divided by 18 is 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 72 from 87 leaves us with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 18

Going ahead to step 3:
If we divide 155 by 18, we get 8 and a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
The remainder is 11 after subtracting 144 from 155.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 18

Moving on to step 4:
The number 18 fits into 110 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 486.0
Deduct 108 from 110 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 18

Going ahead to step 5:
If we divide 26 by 18, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 4861.0
If we take 18 away from 26, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 6:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4861.4
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4861.44
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 4861.44, with a leftover of 0.008.
