We're dividing 80479800 by 666 
Let's see how many times 666 fits into 80479800.

Going ahead to step 1:
666 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 666

Let's proceed to step 2:
666 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 666

Advancing to step 3:
When dividing 804 by 666, we get 1 with a remainder of 138.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 666 away from 804, we end up with 138.
Fetch the next digit (7) from the dividend, attach it to 138 and continue: 1387 / 666

Going ahead to step 4:
When dividing 1387 by 666, we get 2 with a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1332 from 1387, we get 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 666

On to step 5:
If we divide 559 by 666, we get 0 and a remainder of 559.
The next digit of our result is 0. 
Result so far: 120.0
Subtract 0 from 559 to get 559.
Append the next digit (8) from the dividend to 559 and continue with: 5598 / 666

Moving on to step 6:
When dividing 5598 by 666, we get 8 with a remainder of 270.
Use 8 as the next digit of our solution. 
Result so far: 1208.0
The remainder is 270 after subtracting 5328 from 5598.
Fetch the next digit (0) from the dividend, attach it to 270 and continue: 2700 / 666

Moving on to step 7:
When dividing 2700 by 666, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 12084.0
The remainder is 36 after subtracting 2664 from 2700.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 666

Step 8:
666 can be fit into 360 0 times, resulting in a remainder of 360.
The next digit of our result is 0. 
Result so far: 120840.0
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 9:
3600 divided by 666 is 5 with a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 120840.5
Deduct 3330 from 3600 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
666 goes into 2700 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 120840.54
The remainder is 36 after subtracting 2664 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
666 goes into 360 0 times with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 120840.54
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
The number 666 fits into 3600 5 times, leaving a remainder of 270.
Record the quotient 5 as the next digit in the result. 
Result so far: 120840.5405
If we subtract 3330 from 3600, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 13:
666 goes into 2700 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 120840.54054
The remainder is 36 after subtracting 2664 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
When dividing 360 by 666, we get 0 with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 120840.54054
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 15:
666 can be fit into 3600 5 times, resulting in a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 120840.5405405
The remainder is 270 after subtracting 3330 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 16:
666 can be fit into 2700 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 120840.54054054
Deduct 2664 from 2700 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 120840.54054054 and a remainder of 3.6e-08.
