57435249 divided by 666 
Let's see how many times 666 fits into 57435249.

Let's proceed to step 1:
666 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 666

On to step 2:
666 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 666

On to step 3:
574 divided by 666 is 0 with a remainder of 574.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 574 leaves us with 574.
Bring next digit (3) of the dividend behind the 574 and repeat the process: 5743 / 666

On to step 4:
The number 666 fits into 5743 8 times, leaving a remainder of 415.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 5328 from 5743 to get 415.
Bring next digit (5) of the dividend behind the 415 and repeat the process: 4155 / 666

Advancing to step 5:
The number 666 fits into 4155 6 times, leaving a remainder of 159.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 159 after subtracting 3996 from 4155.
Take the next digit (2) from the dividend and append it to 159, then repeat: 1592 / 666

Advancing to step 6:
666 can be fit into 1592 2 times, resulting in a remainder of 260.
Record the quotient 2 as the next digit in the result. 
Result so far: 862.0
If we take 1332 away from 1592, we end up with 260.
Take the next digit (4) from the dividend and append it to 260, then repeat: 2604 / 666

Step 7:
2604 divided by 666 is 3 with a remainder of 606.
Put 3 as the next digit of the answer. 
Result so far: 8623.0
Subtract 1998 from 2604 to get 606.
Include the next digit (9) from the dividend after 606, then repeat: 6069 / 666

Step 8:
666 goes into 6069 9 times with a remainder of 75.
The number 9 becomes the next digit in our result. 
Result so far: 86239.0
If we subtract 5994 from 6069, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
When dividing 750 by 666, we get 1 with a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 86239.1
If we take 666 away from 750, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 10:
When dividing 840 by 666, we get 1 with a remainder of 174.
Use 1 as the next digit of our solution. 
Result so far: 86239.11
Deduct 666 from 840 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The quotient of the division is 86239.11, and the remainder is 0.174.
