We look at the division of 40066 by 1 
We're looking to find how many times 1 goes into 40066.

On to step 1:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 4 from 4 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Let's proceed to step 2:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Let's proceed to step 3:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 400.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Advancing to step 4:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 4006.0
If we take 6 away from 6, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Step 5:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 40066.0
Subtracting 6 from 6 leaves us with 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 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40066.0
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.

Moving on to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40066.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 40066.0 with a balance of 0.0.
