80690328 ÷ 666 
We're looking to find how many times 666 goes into 80690328.

Let's proceed to step 1:
The number 666 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 666

Step 2:
666 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (6) from the dividend, attach it to 80 and continue: 806 / 666

On to step 3:
The number 666 fits into 806 1 times, leaving a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 666 from 806, we get 140.
Bring next digit (9) of the dividend behind the 140 and repeat the process: 1409 / 666

Advancing to step 4:
When dividing 1409 by 666, we get 2 with a remainder of 77.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1332 from 1409 to get 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 666

On to step 5:
770 divided by 666 is 1 with a remainder of 104.
The next digit of our result is 1. 
Result so far: 121.0
If we take 666 away from 770, we end up with 104.
Fetch the next digit (3) from the dividend, attach it to 104 and continue: 1043 / 666

Step 6:
If we divide 1043 by 666, we get 1 and a remainder of 377.
The number 1 becomes the next digit in our result. 
Result so far: 1211.0
If we take 666 away from 1043, we end up with 377.
Bring next digit (2) of the dividend behind the 377 and repeat the process: 3772 / 666

Advancing to step 7:
If we divide 3772 by 666, we get 5 and a remainder of 442.
Use 5 as the next digit of our solution. 
Result so far: 12115.0
Subtracting 3330 from 3772 leaves us with 442.
Bring next digit (8) of the dividend behind the 442 and repeat the process: 4428 / 666

Advancing to step 8:
When dividing 4428 by 666, we get 6 with a remainder of 432.
Put 6 as the next digit of the answer. 
Result so far: 121156.0
If we subtract 3996 from 4428, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 9:
The number 666 fits into 4320 6 times, leaving a remainder of 324.
Put 6 as the next digit of the answer. 
Result so far: 121156.6
Deduct 3996 from 4320 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 10:
If we divide 3240 by 666, we get 4 and a remainder of 576.
The next digit of our result is 4. 
Result so far: 121156.64
The remainder is 576 after subtracting 2664 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 11:
5760 divided by 666 is 8 with a remainder of 432.
The next digit of our result is 8. 
Result so far: 121156.648
Deduct 5328 from 5760 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 12:
If we divide 4320 by 666, we get 6 and a remainder of 324.
The next digit of our result is 6. 
Result so far: 121156.6486
Deduct 3996 from 4320 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 13:
666 can be fit into 3240 4 times, resulting in a remainder of 576.
Write down 4 as next digit of the result. 
Result so far: 121156.64864
Deduct 2664 from 3240 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 14:
666 can be fit into 5760 8 times, resulting in a remainder of 432.
The number 8 becomes the next digit in our result. 
Result so far: 121156.648648
If we subtract 5328 from 5760, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 15:
When dividing 4320 by 666, we get 6 with a remainder of 324.
Record the quotient 6 as the next digit in the result. 
Result so far: 121156.6486486
Deduct 3996 from 4320 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 16:
If we divide 3240 by 666, we get 4 and a remainder of 576.
The next digit of our result is 4. 
Result so far: 121156.64864864
If we take 2664 away from 3240, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

After the division, we end up with 121156.64864864 and a remainder of 5.76e-07.
