1212115 ÷ 623 
Let's see how many times 623 fits into 1212115.

Step 1:
1 divided by 623 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 623

On to step 2:
When dividing 12 by 623, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the 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 / 623

Let's proceed to step 3:
121 divided by 623 is 0 with a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 121, we get 121.
Fetch the next digit (2) from the dividend, attach it to 121 and continue: 1212 / 623

Let's proceed to step 4:
When dividing 1212 by 623, we get 1 with a remainder of 589.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 623 from 1212 leaves us with 589.
Include the next digit (1) from the dividend after 589, then repeat: 5891 / 623

On to step 5:
The number 623 fits into 5891 9 times, leaving a remainder of 284.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 5607 from 5891 and we're left with 284.
Grab the next digit (1) from the dividend, add it to 284, then carry on: 2841 / 623

Step 6:
When dividing 2841 by 623, we get 4 with a remainder of 349.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
Deduct 2492 from 2841 and we're left with 349.
Grab the next digit (5) from the dividend, add it to 349, then carry on: 3495 / 623

Step 7:
623 can be fit into 3495 5 times, resulting in a remainder of 380.
The number 5 becomes the next digit in our result. 
Result so far: 1945.0
Deduct 3115 from 3495 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 8:
The number 623 fits into 3800 6 times, leaving a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 1945.6
If we take 3738 away from 3800, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
When dividing 620 by 623, we get 0 with a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 1945.6
Deduct 0 from 620 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 10:
6200 divided by 623 is 9 with a remainder of 593.
Put 9 as the next digit of the answer. 
Result so far: 1945.609
Subtract 5607 from 6200 to get 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Going ahead to step 11:
623 goes into 5930 9 times with a remainder of 323.
Put 9 as the next digit of the answer. 
Result so far: 1945.6099
The remainder is 323 after subtracting 5607 from 5930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

After the division, we end up with 1945.6099 and a remainder of 0.00323.
