12435767 ÷ 797 
Let's see how many times 797 fits into 12435767.

Advancing to step 1:
If we divide 1 by 797, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 797

On to step 2:
797 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 797

Advancing to step 3:
797 goes into 124 0 times with a remainder of 124.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 124 after subtracting 0 from 124.
Bring next digit (3) of the dividend behind the 124 and repeat the process: 1243 / 797

Step 4:
When dividing 1243 by 797, we get 1 with a remainder of 446.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 446 after subtracting 797 from 1243.
Take the next digit (5) from the dividend and append it to 446, then repeat: 4465 / 797

Moving on to step 5:
797 can be fit into 4465 5 times, resulting in a remainder of 480.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 3985 from 4465, we get 480.
Fetch the next digit (7) from the dividend, attach it to 480 and continue: 4807 / 797

Step 6:
797 goes into 4807 6 times with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Subtract 4782 from 4807 to get 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 797

Advancing to step 7:
256 divided by 797 is 0 with a remainder of 256.
Write down 0 as next digit of the result. 
Result so far: 1560.0
Deduct 0 from 256 and we're left with 256.
Fetch the next digit (7) from the dividend, attach it to 256 and continue: 2567 / 797

On to step 8:
797 goes into 2567 3 times with a remainder of 176.
The number 3 becomes the next digit in our result. 
Result so far: 15603.0
Subtracting 2391 from 2567 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 9:
797 can be fit into 1760 2 times, resulting in a remainder of 166.
Record the quotient 2 as the next digit in the result. 
Result so far: 15603.2
Subtracting 1594 from 1760 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 10:
1660 divided by 797 is 2 with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 15603.22
The remainder is 66 after subtracting 1594 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 15603.22 with a balance of 0.066.
