54931168 ÷ 666 
Let's see how many times 666 fits into 54931168.

Moving on to step 1:
The number 666 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 666

On to step 2:
666 can be fit into 54 0 times, resulting in a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 666

Moving on to step 3:
549 divided by 666 is 0 with a remainder of 549.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 549 leaves us with 549.
Grab the next digit (3) from the dividend, add it to 549, then carry on: 5493 / 666

Going ahead to step 4:
If we divide 5493 by 666, we get 8 and a remainder of 165.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 5328 from 5493 to get 165.
Grab the next digit (1) from the dividend, add it to 165, then carry on: 1651 / 666

Let's proceed to step 5:
The number 666 fits into 1651 2 times, leaving a remainder of 319.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtracting 1332 from 1651 leaves us with 319.
Bring next digit (1) of the dividend behind the 319 and repeat the process: 3191 / 666

Step 6:
The number 666 fits into 3191 4 times, leaving a remainder of 527.
The number 4 becomes the next digit in our result. 
Result so far: 824.0
Subtracting 2664 from 3191 leaves us with 527.
Include the next digit (6) from the dividend after 527, then repeat: 5276 / 666

Step 7:
666 goes into 5276 7 times with a remainder of 614.
Put 7 as the next digit of the answer. 
Result so far: 8247.0
The remainder is 614 after subtracting 4662 from 5276.
Take the next digit (8) from the dividend and append it to 614, then repeat: 6148 / 666

On to step 8:
If we divide 6148 by 666, we get 9 and a remainder of 154.
The next digit of our result is 9. 
Result so far: 82479.0
If we take 5994 away from 6148, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 9:
666 can be fit into 1540 2 times, resulting in a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 82479.2
Subtracting 1332 from 1540 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 10:
2080 divided by 666 is 3 with a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 82479.23
Deduct 1998 from 2080 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
666 can be fit into 820 1 times, resulting in a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 82479.231
The remainder is 154 after subtracting 666 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 12:
666 goes into 1540 2 times with a remainder of 208.
Use 2 as the next digit of our solution. 
Result so far: 82479.2312
Deduct 1332 from 1540 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 13:
When dividing 2080 by 666, we get 3 with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 82479.23123
If we take 1998 away from 2080, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 14:
The number 666 fits into 820 1 times, leaving a remainder of 154.
The number 1 becomes the next digit in our result. 
Result so far: 82479.231231
The remainder is 154 after subtracting 666 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 15:
When dividing 1540 by 666, we get 2 with a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 82479.2312312
Subtracting 1332 from 1540 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 16:
2080 divided by 666 is 3 with a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 82479.23123123
Deduct 1998 from 2080 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The final outcome is 82479.23123123, with a leftover of 8.2e-08.
