87666 ÷ 5 
Let's see how many times 5 fits into 87666.

Step 1:
The number 5 fits into 8 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 5 away from 8, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 5

Moving on to step 2:
The number 5 fits into 37 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 35 away from 37, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 5

Moving on to step 3:
5 goes into 26 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 175.0
If we take 25 away from 26, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 5

On to step 4:
The number 5 fits into 16 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1753.0
Subtracting 15 from 16 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 5

On to step 5:
16 divided by 5 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 17533.0
The remainder is 1 after subtracting 15 from 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
5 can be fit into 10 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 17533.2
Subtract 10 from 10 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
When dividing 0 by 5, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17533.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 17533.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 17533.2 with a remaining 0.0.
