We're dividing 86679485 by 666 
We're looking to find how many times 666 goes into 86679485.

On to step 1:
8 divided by 666 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 666

Step 2:
86 divided by 666 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 666

Advancing to step 3:
666 can be fit into 866 1 times, resulting in a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 200 after subtracting 666 from 866.
Bring next digit (7) of the dividend behind the 200 and repeat the process: 2007 / 666

Let's proceed to step 4:
2007 divided by 666 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1998 from 2007 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 666

On to step 5:
666 can be fit into 99 0 times, resulting in a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 130.0
If we subtract 0 from 99, we get 99.
Fetch the next digit (4) from the dividend, attach it to 99 and continue: 994 / 666

Moving on to step 6:
When dividing 994 by 666, we get 1 with a remainder of 328.
Write down 1 as next digit of the result. 
Result so far: 1301.0
If we subtract 666 from 994, we get 328.
Include the next digit (8) from the dividend after 328, then repeat: 3288 / 666

Step 7:
666 goes into 3288 4 times with a remainder of 624.
Write down 4 as next digit of the result. 
Result so far: 13014.0
The remainder is 624 after subtracting 2664 from 3288.
Grab the next digit (5) from the dividend, add it to 624, then carry on: 6245 / 666

Advancing to step 8:
6245 divided by 666 is 9 with a remainder of 251.
The next digit of our result is 9. 
Result so far: 130149.0
Subtracting 5994 from 6245 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 9:
2510 divided by 666 is 3 with a remainder of 512.
Record the quotient 3 as the next digit in the result. 
Result so far: 130149.3
If we take 1998 away from 2510, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 10:
666 goes into 5120 7 times with a remainder of 458.
The next digit of our result is 7. 
Result so far: 130149.37
If we take 4662 away from 5120, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 11:
4580 divided by 666 is 6 with a remainder of 584.
The next digit of our result is 6. 
Result so far: 130149.376
Deduct 3996 from 4580 and we're left with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Going ahead to step 12:
When dividing 5840 by 666, we get 8 with a remainder of 512.
The number 8 becomes the next digit in our result. 
Result so far: 130149.3768
If we take 5328 away from 5840, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 13:
5120 divided by 666 is 7 with a remainder of 458.
Record the quotient 7 as the next digit in the result. 
Result so far: 130149.37687
Subtract 4662 from 5120 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Going ahead to step 14:
4580 divided by 666 is 6 with a remainder of 584.
Use 6 as the next digit of our solution. 
Result so far: 130149.376876
Subtracting 3996 from 4580 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 15:
5840 divided by 666 is 8 with a remainder of 512.
The next digit of our result is 8. 
Result so far: 130149.3768768
If we take 5328 away from 5840, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 16:
The number 666 fits into 5120 7 times, leaving a remainder of 458.
Record the quotient 7 as the next digit in the result. 
Result so far: 130149.37687687
Deduct 4662 from 5120 and we're left with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

The quotient of the division is 130149.37687687, and the remainder is 4.58e-07.
