Let's divide 12345597 by 240
Let's see how many times 240 fits into 12345597.

Step 1:
1 divided by 240 is 0 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 / 240

Let's proceed to step 2:
240 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
If we subtract 0 from 12, we get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 240

Let's proceed to step 3:
The number 240 fits into 123 0 times, leaving a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 123 after subtracting 0 from 123.
Include the next digit (4) from the dividend after 123, then repeat: 1234 / 240

On to step 4:
240 can be fit into 1234 5 times, resulting in a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 1200 from 1234 and we're left with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 240

Advancing to step 5:
345 divided by 240 is 1 with a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 240 from 345 and we're left with 105.
Take the next digit (5) from the dividend and append it to 105, then repeat: 1055 / 240

Step 6:
1055 divided by 240 is 4 with a remainder of 95.
The number 4 becomes the next digit in our result. 
Result so far: 514.0
Deduct 960 from 1055 and we're left with 95.
Append the next digit (9) from the dividend to 95 and continue with: 959 / 240

Step 7:
240 goes into 959 3 times with a remainder of 239.
The number 3 becomes the next digit in our result. 
Result so far: 5143.0
If we subtract 720 from 959, we get 239.
Include the next digit (7) from the dividend after 239, then repeat: 2397 / 240

Advancing to step 8:
The number 240 fits into 2397 9 times, leaving a remainder of 237.
Use 9 as the next digit of our solution. 
Result so far: 51439.0
Deduct 2160 from 2397 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Going ahead to step 9:
When dividing 2370 by 240, we get 9 with a remainder of 210.
Write down 9 as next digit of the result. 
Result so far: 51439.9
Subtracting 2160 from 2370 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 10:
The number 240 fits into 2100 8 times, leaving a remainder of 180.
The next digit of our result is 8. 
Result so far: 51439.98
Deduct 1920 from 2100 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
240 can be fit into 1800 7 times, resulting in a remainder of 120.
The next digit of our result is 7. 
Result so far: 51439.987
If we take 1680 away from 1800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
The number 240 fits into 1200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 51439.9875
Deduct 1200 from 1200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
0 divided by 240 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 51439.9875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 14:
The number 240 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51439.9875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 51439.9875, and the remainder is 0.0.
