9205129 ÷ 666 
Let's see how many times 666 fits into 9205129.

Let's proceed to step 1:
If we divide 9 by 666, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 666

Moving on to step 2:
666 goes into 92 0 times with a remainder of 92.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 92 leaves us with 92.
Append the next digit (0) from the dividend to 92 and continue with: 920 / 666

Advancing to step 3:
666 goes into 920 1 times with a remainder of 254.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 666 from 920 and we're left with 254.
Take the next digit (5) from the dividend and append it to 254, then repeat: 2545 / 666

Moving on to step 4:
The number 666 fits into 2545 3 times, leaving a remainder of 547.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1998 from 2545 to get 547.
Take the next digit (1) from the dividend and append it to 547, then repeat: 5471 / 666

Let's proceed to step 5:
If we divide 5471 by 666, we get 8 and a remainder of 143.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtract 5328 from 5471 to get 143.
Include the next digit (2) from the dividend after 143, then repeat: 1432 / 666

Going ahead to step 6:
If we divide 1432 by 666, we get 2 and a remainder of 100.
The next digit of our result is 2. 
Result so far: 1382.0
Subtracting 1332 from 1432 leaves us with 100.
Bring next digit (9) of the dividend behind the 100 and repeat the process: 1009 / 666

Step 7:
When dividing 1009 by 666, we get 1 with a remainder of 343.
Record the quotient 1 as the next digit in the result. 
Result so far: 13821.0
If we take 666 away from 1009, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 8:
The number 666 fits into 3430 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 13821.5
If we subtract 3330 from 3430, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 9:
If we divide 1000 by 666, we get 1 and a remainder of 334.
Use 1 as the next digit of our solution. 
Result so far: 13821.51
The remainder is 334 after subtracting 666 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 10:
666 goes into 3340 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 13821.515
Subtracting 3330 from 3340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 666 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 13821.515
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
The number 666 fits into 1000 1 times, leaving a remainder of 334.
Write down 1 as next digit of the result. 
Result so far: 13821.51501
If we subtract 666 from 1000, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 13:
666 can be fit into 3340 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 13821.515015
If we subtract 3330 from 3340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
666 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 13821.515015
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
If we divide 1000 by 666, we get 1 and a remainder of 334.
The next digit of our result is 1. 
Result so far: 13821.51501501
If we subtract 666 from 1000, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

In conclusion, the division gives 13821.51501501 with a balance of 3.34e-07.
