12105020 divided by 723 
We're looking to find how many times 723 goes into 12105020.

Moving on to step 1:
723 goes into 1 0 times 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.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 723

Going ahead to step 2:
723 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 723

Step 3:
When dividing 121 by 723, we get 0 with a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 121 to get 121.
Append the next digit (0) from the dividend to 121 and continue with: 1210 / 723

Let's proceed to step 4:
When dividing 1210 by 723, we get 1 with a remainder of 487.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 723 from 1210 and we're left with 487.
Append the next digit (5) from the dividend to 487 and continue with: 4875 / 723

Advancing to step 5:
If we divide 4875 by 723, we get 6 and a remainder of 537.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 4338 from 4875 and we're left with 537.
Include the next digit (0) from the dividend after 537, then repeat: 5370 / 723

Let's proceed to step 6:
If we divide 5370 by 723, we get 7 and a remainder of 309.
The next digit of our result is 7. 
Result so far: 167.0
Deduct 5061 from 5370 and we're left with 309.
Bring next digit (2) of the dividend behind the 309 and repeat the process: 3092 / 723

Advancing to step 7:
723 can be fit into 3092 4 times, resulting in a remainder of 200.
The number 4 becomes the next digit in our result. 
Result so far: 1674.0
Subtract 2892 from 3092 to get 200.
Grab the next digit (0) from the dividend, add it to 200, then carry on: 2000 / 723

Let's proceed to step 8:
When dividing 2000 by 723, we get 2 with a remainder of 554.
Write down 2 as next digit of the result. 
Result so far: 16742.0
The remainder is 554 after subtracting 1446 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Let's proceed to step 9:
5540 divided by 723 is 7 with a remainder of 479.
The next digit of our result is 7. 
Result so far: 16742.7
If we take 5061 away from 5540, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Going ahead to step 10:
723 goes into 4790 6 times with a remainder of 452.
Put 6 as the next digit of the answer. 
Result so far: 16742.76
Subtracting 4338 from 4790 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 11:
723 goes into 4520 6 times with a remainder of 182.
Record the quotient 6 as the next digit in the result. 
Result so far: 16742.766
Subtract 4338 from 4520 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

After the division, we end up with 16742.766 and a remainder of 0.0182.
