28705316 ÷ 666 
We want to figure out the number of times 28705316 can be divided by 666.

Let's proceed to step 1:
2 divided by 666 is 0 with 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.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 666

Step 2:
666 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 666

On to step 3:
If we divide 287 by 666, we get 0 and a remainder of 287.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 287 and we're left with 287.
Fetch the next digit (0) from the dividend, attach it to 287 and continue: 2870 / 666

Step 4:
The number 666 fits into 2870 4 times, leaving a remainder of 206.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2664 from 2870 and we're left with 206.
Include the next digit (5) from the dividend after 206, then repeat: 2065 / 666

Let's proceed to step 5:
If we divide 2065 by 666, we get 3 and a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 67 after subtracting 1998 from 2065.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 666

Moving on to step 6:
When dividing 673 by 666, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 431.0
Subtracting 666 from 673 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 666

Step 7:
666 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 4310.0
If we take 0 away from 71, we end up with 71.
Fetch the next digit (6) from the dividend, attach it to 71 and continue: 716 / 666

Advancing to step 8:
666 goes into 716 1 times with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 43101.0
If we subtract 666 from 716, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
500 divided by 666 is 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 43101.0
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
If we divide 5000 by 666, we get 7 and a remainder of 338.
Write down 7 as next digit of the result. 
Result so far: 43101.07
Deduct 4662 from 5000 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 11:
666 can be fit into 3380 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 43101.075
If we subtract 3330 from 3380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
The number 666 fits into 500 0 times, leaving a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 43101.075
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 13:
666 can be fit into 5000 7 times, resulting in a remainder of 338.
Use 7 as the next digit of our solution. 
Result so far: 43101.07507
Deduct 4662 from 5000 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 14:
666 goes into 3380 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 43101.075075
If we take 3330 away from 3380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
666 goes into 500 0 times with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 43101.075075
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 16:
666 goes into 5000 7 times with a remainder of 338.
The next digit of our result is 7. 
Result so far: 43101.07507507
If we subtract 4662 from 5000, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

The final outcome is 43101.07507507, with a leftover of 3.38e-07.
