Let's divide 11418590 by 666
We want to divide 11418590 by 666.

Advancing to step 1:
1 divided by 666 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 666

Step 2:
The number 666 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 666

Step 3:
If we divide 114 by 666, we get 0 and a remainder of 114.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 114 leaves us with 114.
Append the next digit (1) from the dividend to 114 and continue with: 1141 / 666

Going ahead to step 4:
666 can be fit into 1141 1 times, resulting in a remainder of 475.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 475 after subtracting 666 from 1141.
Include the next digit (8) from the dividend after 475, then repeat: 4758 / 666

Let's proceed to step 5:
4758 divided by 666 is 7 with a remainder of 96.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 4662 from 4758 to get 96.
Grab the next digit (5) from the dividend, add it to 96, then carry on: 965 / 666

Going ahead to step 6:
The number 666 fits into 965 1 times, leaving a remainder of 299.
Write down 1 as next digit of the result. 
Result so far: 171.0
Subtract 666 from 965 to get 299.
Grab the next digit (9) from the dividend, add it to 299, then carry on: 2999 / 666

Step 7:
If we divide 2999 by 666, we get 4 and a remainder of 335.
The number 4 becomes the next digit in our result. 
Result so far: 1714.0
The remainder is 335 after subtracting 2664 from 2999.
Bring next digit (0) of the dividend behind the 335 and repeat the process: 3350 / 666

Going ahead to step 8:
When dividing 3350 by 666, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 17145.0
If we take 3330 away from 3350, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
666 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 17145.0
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
666 goes into 2000 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 17145.03
If we take 1998 away from 2000, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
If we divide 20 by 666, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 17145.03
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
The number 666 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 17145.03
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 17145.03 and a remainder of 0.002.
