We look at the division of 76666 by 18 
We want to figure out the number of times 76666 can be divided by 18.

Step 1:
When dividing 7 by 18, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 18

Going ahead to step 2:
If we divide 76 by 18, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 72 from 76 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 18

On to step 3:
46 divided by 18 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 36 from 46 leaves us with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 18

Moving on to step 4:
106 divided by 18 is 5 with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 425.0
If we take 90 away from 106, we end up with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 18

Moving on to step 5:
When dividing 166 by 18, we get 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 4259.0
Subtract 162 from 166 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 6:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 4259.2
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
18 can be fit into 40 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 4259.22
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 4259.22 with a remaining 0.004.
