10558750 divided by 666 
Our goal is to divide 10558750 by 666.

Let's proceed to step 1:
The number 666 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 666

Advancing to step 2:
When dividing 10 by 666, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 666

Advancing to step 3:
When dividing 105 by 666, we get 0 with a remainder of 105.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 105 leaves us with 105.
Include the next digit (5) from the dividend after 105, then repeat: 1055 / 666

Step 4:
When dividing 1055 by 666, we get 1 with a remainder of 389.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 666 from 1055 and we're left with 389.
Include the next digit (8) from the dividend after 389, then repeat: 3898 / 666

Advancing to step 5:
If we divide 3898 by 666, we get 5 and a remainder of 568.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 3330 from 3898 to get 568.
Bring next digit (7) of the dividend behind the 568 and repeat the process: 5687 / 666

Moving on to step 6:
The number 666 fits into 5687 8 times, leaving a remainder of 359.
Use 8 as the next digit of our solution. 
Result so far: 158.0
Subtract 5328 from 5687 to get 359.
Grab the next digit (5) from the dividend, add it to 359, then carry on: 3595 / 666

On to step 7:
666 can be fit into 3595 5 times, resulting in a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 1585.0
Deduct 3330 from 3595 and we're left with 265.
Append the next digit (0) from the dividend to 265 and continue with: 2650 / 666

Going ahead to step 8:
666 can be fit into 2650 3 times, resulting in a remainder of 652.
The next digit of our result is 3. 
Result so far: 15853.0
Subtract 1998 from 2650 to get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Let's proceed to step 9:
666 goes into 6520 9 times with a remainder of 526.
Use 9 as the next digit of our solution. 
Result so far: 15853.9
If we subtract 5994 from 6520, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 10:
If we divide 5260 by 666, we get 7 and a remainder of 598.
Put 7 as the next digit of the answer. 
Result so far: 15853.97
Subtracting 4662 from 5260 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 11:
666 goes into 5980 8 times with a remainder of 652.
Write down 8 as next digit of the result. 
Result so far: 15853.978
Subtract 5328 from 5980 to get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Step 12:
The number 666 fits into 6520 9 times, leaving a remainder of 526.
The number 9 becomes the next digit in our result. 
Result so far: 15853.9789
Subtract 5994 from 6520 to get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

On to step 13:
666 goes into 5260 7 times with a remainder of 598.
Record the quotient 7 as the next digit in the result. 
Result so far: 15853.97897
Deduct 4662 from 5260 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

On to step 14:
5980 divided by 666 is 8 with a remainder of 652.
Record the quotient 8 as the next digit in the result. 
Result so far: 15853.978978
Subtracting 5328 from 5980 leaves us with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Advancing to step 15:
6520 divided by 666 is 9 with a remainder of 526.
The next digit of our result is 9. 
Result so far: 15853.9789789
Subtract 5994 from 6520 to get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Step 16:
666 can be fit into 5260 7 times, resulting in a remainder of 598.
Put 7 as the next digit of the answer. 
Result so far: 15853.97897897
If we take 4662 away from 5260, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Our division results in 15853.97897897 with a remaining 5.98e-07.
