803177 divided by 666 
We want to figure out the number of times 803177 can be divided by 666.

Step 1:
If we divide 8 by 666, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 666

On to step 2:
80 divided by 666 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 666

Let's proceed to step 3:
666 can be fit into 803 1 times, resulting in a remainder of 137.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 666 from 803 leaves us with 137.
Take the next digit (1) from the dividend and append it to 137, then repeat: 1371 / 666

Moving on to step 4:
1371 divided by 666 is 2 with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1332 from 1371 leaves us with 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 666

Advancing to step 5:
The number 666 fits into 397 0 times, leaving a remainder of 397.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
Subtract 0 from 397 to get 397.
Bring next digit (7) of the dividend behind the 397 and repeat the process: 3977 / 666

Step 6:
The number 666 fits into 3977 5 times, leaving a remainder of 647.
Use 5 as the next digit of our solution. 
Result so far: 1205.0
Subtract 3330 from 3977 to get 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Step 7:
666 goes into 6470 9 times with a remainder of 476.
Put 9 as the next digit of the answer. 
Result so far: 1205.9
Deduct 5994 from 6470 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 8:
666 goes into 4760 7 times with a remainder of 98.
The number 7 becomes the next digit in our result. 
Result so far: 1205.97
Subtracting 4662 from 4760 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 9:
980 divided by 666 is 1 with a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 1205.971
Subtract 666 from 980 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 10:
If we divide 3140 by 666, we get 4 and a remainder of 476.
The next digit of our result is 4. 
Result so far: 1205.9714
The remainder is 476 after subtracting 2664 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 11:
When dividing 4760 by 666, we get 7 with a remainder of 98.
The number 7 becomes the next digit in our result. 
Result so far: 1205.97147
The remainder is 98 after subtracting 4662 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 12:
If we divide 980 by 666, we get 1 and a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 1205.971471
Subtracting 666 from 980 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 13:
If we divide 3140 by 666, we get 4 and a remainder of 476.
The next digit of our result is 4. 
Result so far: 1205.9714714
The remainder is 476 after subtracting 2664 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 14:
666 can be fit into 4760 7 times, resulting in a remainder of 98.
The next digit of our result is 7. 
Result so far: 1205.97147147
Subtract 4662 from 4760 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final outcome is 1205.97147147, with a leftover of 9.8e-08.
