12000511 ÷ 123 
We're looking to find how many times 123 goes into 12000511.

Let's proceed to step 1:
123 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 123

Moving on to step 2:
12 divided by 123 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 123

Let's proceed to step 3:
The number 123 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 120 leaves us with 120.
Bring next digit (0) of the dividend behind the 120 and repeat the process: 1200 / 123

On to step 4:
123 can be fit into 1200 9 times, resulting in a remainder of 93.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 1107 from 1200 leaves us with 93.
Bring next digit (0) of the dividend behind the 93 and repeat the process: 930 / 123

Going ahead to step 5:
930 divided by 123 is 7 with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtract 861 from 930 to get 69.
Include the next digit (5) from the dividend after 69, then repeat: 695 / 123

Advancing to step 6:
695 divided by 123 is 5 with a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 975.0
If we subtract 615 from 695, we get 80.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 123

Moving on to step 7:
If we divide 801 by 123, we get 6 and a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 9756.0
The remainder is 63 after subtracting 738 from 801.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 123

On to step 8:
123 can be fit into 631 5 times, resulting in a remainder of 16.
The next digit of our result is 5. 
Result so far: 97565.0
The remainder is 16 after subtracting 615 from 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
If we divide 160 by 123, we get 1 and a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 97565.1
Subtracting 123 from 160 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
123 goes into 370 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 97565.13
Subtracting 369 from 370 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
123 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 97565.13
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 123, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 97565.13
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 97565.13 with a remainder of 0.001.
