24640516 ÷ 123 
We want to figure out the number of times 24640516 can be divided by 123.

Let's proceed to step 1:
123 goes into 2 0 times 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.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 123

Let's proceed to step 2:
The number 123 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 123

Step 3:
123 goes into 246 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 246 from 246 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 123

Let's proceed to step 4:
The number 123 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 123

On to step 5:
123 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 200.0
If we subtract 0 from 40, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 123

On to step 6:
123 can be fit into 405 3 times, resulting in a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 2003.0
If we subtract 369 from 405, we get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 123

Advancing to step 7:
123 goes into 361 2 times with a remainder of 115.
Write down 2 as next digit of the result. 
Result so far: 20032.0
Subtract 246 from 361 to get 115.
Grab the next digit (6) from the dividend, add it to 115, then carry on: 1156 / 123

Moving on to step 8:
123 can be fit into 1156 9 times, resulting in a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 200329.0
Subtract 1107 from 1156 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
123 can be fit into 490 3 times, resulting in a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 200329.3
Subtracting 369 from 490 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 10:
When dividing 1210 by 123, we get 9 with a remainder of 103.
The next digit of our result is 9. 
Result so far: 200329.39
Subtracting 1107 from 1210 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 11:
123 can be fit into 1030 8 times, resulting in a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 200329.398
Deduct 984 from 1030 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 12:
The number 123 fits into 460 3 times, leaving a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 200329.3983
Subtract 369 from 460 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 13:
When dividing 910 by 123, we get 7 with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 200329.39837
If we subtract 861 from 910, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
If we divide 490 by 123, we get 3 and a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 200329.398373
Subtracting 369 from 490 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 15:
When dividing 1210 by 123, we get 9 with a remainder of 103.
Record the quotient 9 as the next digit in the result. 
Result so far: 200329.3983739
Deduct 1107 from 1210 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 16:
The number 123 fits into 1030 8 times, leaving a remainder of 46.
The next digit of our result is 8. 
Result so far: 200329.39837398
Subtract 984 from 1030 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 200329.39837398, with a leftover of 4.6e-08.
