We divide 12391216 by 505
Our goal is to divide 12391216 by 505.

Moving on to step 1:
1 divided by 505 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 505

Moving on to step 2:
If we divide 12 by 505, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 505

Moving on to step 3:
123 divided by 505 is 0 with a remainder of 123.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 123 to get 123.
Bring next digit (9) of the dividend behind the 123 and repeat the process: 1239 / 505

Step 4:
1239 divided by 505 is 2 with a remainder of 229.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1010 from 1239, we get 229.
Take the next digit (1) from the dividend and append it to 229, then repeat: 2291 / 505

Advancing to step 5:
When dividing 2291 by 505, we get 4 with a remainder of 271.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 2020 away from 2291, we end up with 271.
Fetch the next digit (2) from the dividend, attach it to 271 and continue: 2712 / 505

Step 6:
The number 505 fits into 2712 5 times, leaving a remainder of 187.
Put 5 as the next digit of the answer. 
Result so far: 245.0
Deduct 2525 from 2712 and we're left with 187.
Bring next digit (1) of the dividend behind the 187 and repeat the process: 1871 / 505

Moving on to step 7:
505 goes into 1871 3 times with a remainder of 356.
Write down 3 as next digit of the result. 
Result so far: 2453.0
Subtract 1515 from 1871 to get 356.
Include the next digit (6) from the dividend after 356, then repeat: 3566 / 505

Step 8:
The number 505 fits into 3566 7 times, leaving a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 24537.0
Deduct 3535 from 3566 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
When dividing 310 by 505, we get 0 with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 24537.0
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
505 can be fit into 3100 6 times, resulting in a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 24537.06
If we take 3030 away from 3100, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
700 divided by 505 is 1 with a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 24537.061
If we subtract 505 from 700, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 12:
505 can be fit into 1950 3 times, resulting in a remainder of 435.
Use 3 as the next digit of our solution. 
Result so far: 24537.0613
The remainder is 435 after subtracting 1515 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 13:
505 can be fit into 4350 8 times, resulting in a remainder of 310.
The number 8 becomes the next digit in our result. 
Result so far: 24537.06138
The remainder is 310 after subtracting 4040 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 14:
If we divide 3100 by 505, we get 6 and a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 24537.061386
Subtracting 3030 from 3100 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
505 can be fit into 700 1 times, resulting in a remainder of 195.
The next digit of our result is 1. 
Result so far: 24537.0613861
Deduct 505 from 700 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 16:
When dividing 1950 by 505, we get 3 with a remainder of 435.
Use 3 as the next digit of our solution. 
Result so far: 24537.06138613
Subtract 1515 from 1950 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

The final result is 24537.06138613 with a remainder of 4.35e-07.
