12495205 divided by 623 
Our goal is to divide 12495205 by 623.

On to step 1:
1 divided by 623 is 0 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.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 623

Advancing to step 2:
623 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 623

Step 3:
623 can be fit into 124 0 times, resulting in a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Include the next digit (9) from the dividend after 124, then repeat: 1249 / 623

On to step 4:
1249 divided by 623 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1246 from 1249 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 623

Step 5:
623 goes into 35 0 times with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 623

Going ahead to step 6:
When dividing 352 by 623, we get 0 with a remainder of 352.
Use 0 as the next digit of our solution. 
Result so far: 200.0
The remainder is 352 after subtracting 0 from 352.
Fetch the next digit (0) from the dividend, attach it to 352 and continue: 3520 / 623

Step 7:
When dividing 3520 by 623, we get 5 with a remainder of 405.
The next digit of our result is 5. 
Result so far: 2005.0
Deduct 3115 from 3520 and we're left with 405.
Bring next digit (5) of the dividend behind the 405 and repeat the process: 4055 / 623

Step 8:
When dividing 4055 by 623, we get 6 with a remainder of 317.
Write down 6 as next digit of the result. 
Result so far: 20056.0
If we subtract 3738 from 4055, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 9:
When dividing 3170 by 623, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 20056.5
The remainder is 55 after subtracting 3115 from 3170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
623 goes into 550 0 times with a remainder of 550.
The number 0 becomes the next digit in our result. 
Result so far: 20056.5
Subtracting 0 from 550 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 11:
5500 divided by 623 is 8 with a remainder of 516.
Put 8 as the next digit of the answer. 
Result so far: 20056.508
Subtracting 4984 from 5500 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 12:
When dividing 5160 by 623, we get 8 with a remainder of 176.
Use 8 as the next digit of our solution. 
Result so far: 20056.5088
Subtract 4984 from 5160 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The quotient of the division is 20056.5088, and the remainder is 0.00176.
