20459073 ÷ 666 
We're looking to find how many times 666 goes into 20459073.

Advancing to step 1:
666 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 666

Step 2:
666 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 666

Let's proceed to step 3:
When dividing 204 by 666, we get 0 with a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 204 and we're left with 204.
Grab the next digit (5) from the dividend, add it to 204, then carry on: 2045 / 666

Step 4:
The number 666 fits into 2045 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1998 away from 2045, we end up with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 666

Step 5:
666 can be fit into 479 0 times, resulting in a remainder of 479.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 479 and we're left with 479.
Fetch the next digit (0) from the dividend, attach it to 479 and continue: 4790 / 666

Advancing to step 6:
The number 666 fits into 4790 7 times, leaving a remainder of 128.
Write down 7 as next digit of the result. 
Result so far: 307.0
If we take 4662 away from 4790, we end up with 128.
Append the next digit (7) from the dividend to 128 and continue with: 1287 / 666

Moving on to step 7:
If we divide 1287 by 666, we get 1 and a remainder of 621.
Write down 1 as next digit of the result. 
Result so far: 3071.0
If we take 666 away from 1287, we end up with 621.
Bring next digit (3) of the dividend behind the 621 and repeat the process: 6213 / 666

Advancing to step 8:
If we divide 6213 by 666, we get 9 and a remainder of 219.
Record the quotient 9 as the next digit in the result. 
Result so far: 30719.0
If we take 5994 away from 6213, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 9:
2190 divided by 666 is 3 with a remainder of 192.
Write down 3 as next digit of the result. 
Result so far: 30719.3
If we subtract 1998 from 2190, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 10:
If we divide 1920 by 666, we get 2 and a remainder of 588.
Put 2 as the next digit of the answer. 
Result so far: 30719.32
Deduct 1332 from 1920 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 11:
5880 divided by 666 is 8 with a remainder of 552.
The number 8 becomes the next digit in our result. 
Result so far: 30719.328
Subtract 5328 from 5880 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 12:
If we divide 5520 by 666, we get 8 and a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 30719.3288
Subtracting 5328 from 5520 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 30719.3288 with a remainder of 0.00192.
