252488 ÷ 666 
Let's see how many times 666 fits into 252488.

Moving on to step 1:
If we divide 2 by 666, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 666

Let's proceed to step 2:
666 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 666

Let's proceed to step 3:
If we divide 252 by 666, we get 0 and a remainder of 252.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 252 after subtracting 0 from 252.
Append the next digit (4) from the dividend to 252 and continue with: 2524 / 666

Let's proceed to step 4:
When dividing 2524 by 666, we get 3 with a remainder of 526.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1998 from 2524 leaves us with 526.
Append the next digit (8) from the dividend to 526 and continue with: 5268 / 666

On to step 5:
666 goes into 5268 7 times with a remainder of 606.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 4662 away from 5268, we end up with 606.
Include the next digit (8) from the dividend after 606, then repeat: 6068 / 666

Going ahead to step 6:
6068 divided by 666 is 9 with a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 379.0
Subtract 5994 from 6068 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
666 goes into 740 1 times with a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 379.1
If we subtract 666 from 740, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
The number 666 fits into 740 1 times, leaving a remainder of 74.
The next digit of our result is 1. 
Result so far: 379.11
Deduct 666 from 740 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 379.11 with a remainder of 0.074.
