11819079 ÷ 999 
Let's see how many times 999 fits into 11819079.

On to step 1:
When dividing 1 by 999, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 999

Step 2:
The number 999 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 999

Let's proceed to step 3:
The number 999 fits into 118 0 times, leaving a remainder of 118.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 118, we end up with 118.
Append the next digit (1) from the dividend to 118 and continue with: 1181 / 999

Going ahead to step 4:
999 goes into 1181 1 times with a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 999 from 1181 to get 182.
Bring next digit (9) of the dividend behind the 182 and repeat the process: 1829 / 999

Step 5:
999 goes into 1829 1 times with a remainder of 830.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 999 from 1829, we get 830.
Append the next digit (0) from the dividend to 830 and continue with: 8300 / 999

Moving on to step 6:
If we divide 8300 by 999, we get 8 and a remainder of 308.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtracting 7992 from 8300 leaves us with 308.
Bring next digit (7) of the dividend behind the 308 and repeat the process: 3087 / 999

On to step 7:
The number 999 fits into 3087 3 times, leaving a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 1183.0
If we take 2997 away from 3087, we end up with 90.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 999

On to step 8:
The number 999 fits into 909 0 times, leaving a remainder of 909.
Use 0 as the next digit of our solution. 
Result so far: 11830.0
If we take 0 away from 909, we end up with 909.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9090, and continue the process.

Step 9:
The number 999 fits into 9090 9 times, leaving a remainder of 99.
Record the quotient 9 as the next digit in the result. 
Result so far: 11830.9
Subtract 8991 from 9090 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 10:
If we divide 990 by 999, we get 0 and a remainder of 990.
Write down 0 as next digit of the result. 
Result so far: 11830.9
Deduct 0 from 990 and we're left with 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9900, and continue the process.

Advancing to step 11:
When dividing 9900 by 999, we get 9 with a remainder of 909.
Put 9 as the next digit of the answer. 
Result so far: 11830.909
If we subtract 8991 from 9900, we get 909.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9090, and continue the process.

On to step 12:
999 goes into 9090 9 times with a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 11830.9099
If we take 8991 away from 9090, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

After the division, we end up with 11830.9099 and a remainder of 0.00099.
