24005099 ÷ 138 
We're looking to find how many times 138 goes into 24005099.

Let's proceed to step 1:
138 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 138

Moving on to step 2:
138 goes into 24 0 times with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 138

Step 3:
The number 138 fits into 240 1 times, leaving a remainder of 102.
The next digit of our result is 1. 
Result so far: 1.0
If we take 138 away from 240, we end up with 102.
Take the next digit (0) from the dividend and append it to 102, then repeat: 1020 / 138

Step 4:
The number 138 fits into 1020 7 times, leaving a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 966 from 1020 leaves us with 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 138

Let's proceed to step 5:
The number 138 fits into 545 3 times, leaving a remainder of 131.
Put 3 as the next digit of the answer. 
Result so far: 173.0
If we subtract 414 from 545, we get 131.
Grab the next digit (0) from the dividend, add it to 131, then carry on: 1310 / 138

Going ahead to step 6:
138 can be fit into 1310 9 times, resulting in a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 1739.0
The remainder is 68 after subtracting 1242 from 1310.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 138

Moving on to step 7:
138 can be fit into 689 4 times, resulting in a remainder of 137.
Record the quotient 4 as the next digit in the result. 
Result so far: 17394.0
The remainder is 137 after subtracting 552 from 689.
Include the next digit (9) from the dividend after 137, then repeat: 1379 / 138

Let's proceed to step 8:
1379 divided by 138 is 9 with a remainder of 137.
The number 9 becomes the next digit in our result. 
Result so far: 173949.0
Subtract 1242 from 1379 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 9:
The number 138 fits into 1370 9 times, leaving a remainder of 128.
Use 9 as the next digit of our solution. 
Result so far: 173949.9
Subtract 1242 from 1370 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 10:
The number 138 fits into 1280 9 times, leaving a remainder of 38.
The next digit of our result is 9. 
Result so far: 173949.99
The remainder is 38 after subtracting 1242 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 173949.99, with a leftover of 0.038.
