Let's divide 25748858 by 666
Our goal is to divide 25748858 by 666.

Step 1:
2 divided by 666 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 666

Step 2:
If we divide 25 by 666, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 666

Moving on to step 3:
257 divided by 666 is 0 with a remainder of 257.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 257 and we're left with 257.
Fetch the next digit (4) from the dividend, attach it to 257 and continue: 2574 / 666

On to step 4:
666 goes into 2574 3 times with a remainder of 576.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1998 from 2574 leaves us with 576.
Fetch the next digit (8) from the dividend, attach it to 576 and continue: 5768 / 666

Let's proceed to step 5:
When dividing 5768 by 666, we get 8 with a remainder of 440.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 5328 from 5768 to get 440.
Append the next digit (8) from the dividend to 440 and continue with: 4408 / 666

Let's proceed to step 6:
The number 666 fits into 4408 6 times, leaving a remainder of 412.
The next digit of our result is 6. 
Result so far: 386.0
Subtracting 3996 from 4408 leaves us with 412.
Bring next digit (5) of the dividend behind the 412 and repeat the process: 4125 / 666

Going ahead to step 7:
666 goes into 4125 6 times with a remainder of 129.
Record the quotient 6 as the next digit in the result. 
Result so far: 3866.0
If we subtract 3996 from 4125, we get 129.
Take the next digit (8) from the dividend and append it to 129, then repeat: 1298 / 666

Moving on to step 8:
666 goes into 1298 1 times with a remainder of 632.
Record the quotient 1 as the next digit in the result. 
Result so far: 38661.0
Subtract 666 from 1298 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 9:
When dividing 6320 by 666, we get 9 with a remainder of 326.
Put 9 as the next digit of the answer. 
Result so far: 38661.9
Subtract 5994 from 6320 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 10:
666 goes into 3260 4 times with a remainder of 596.
The next digit of our result is 4. 
Result so far: 38661.94
The remainder is 596 after subtracting 2664 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 11:
If we divide 5960 by 666, we get 8 and a remainder of 632.
Write down 8 as next digit of the result. 
Result so far: 38661.948
The remainder is 632 after subtracting 5328 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Moving on to step 12:
6320 divided by 666 is 9 with a remainder of 326.
Write down 9 as next digit of the result. 
Result so far: 38661.9489
If we take 5994 away from 6320, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 13:
If we divide 3260 by 666, we get 4 and a remainder of 596.
Write down 4 as next digit of the result. 
Result so far: 38661.94894
If we take 2664 away from 3260, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 14:
666 can be fit into 5960 8 times, resulting in a remainder of 632.
Use 8 as the next digit of our solution. 
Result so far: 38661.948948
Subtract 5328 from 5960 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 15:
666 goes into 6320 9 times with a remainder of 326.
Put 9 as the next digit of the answer. 
Result so far: 38661.9489489
Subtracting 5994 from 6320 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 16:
When dividing 3260 by 666, we get 4 with a remainder of 596.
Record the quotient 4 as the next digit in the result. 
Result so far: 38661.94894894
Subtract 2664 from 3260 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

In conclusion, the division gives 38661.94894894 with a balance of 5.96e-07.
