12247610 ÷ 397 
We want to divide 12247610 by 397.

Going ahead to step 1:
The number 397 fits into 1 0 times, leaving 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.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 397

Moving on to step 2:
397 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 397

Step 3:
122 divided by 397 is 0 with a remainder of 122.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 122 after subtracting 0 from 122.
Grab the next digit (4) from the dividend, add it to 122, then carry on: 1224 / 397

Going ahead to step 4:
The number 397 fits into 1224 3 times, leaving a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 1191 from 1224 to get 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 397

Going ahead to step 5:
When dividing 337 by 397, we get 0 with a remainder of 337.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 337, we end up with 337.
Include the next digit (6) from the dividend after 337, then repeat: 3376 / 397

On to step 6:
The number 397 fits into 3376 8 times, leaving a remainder of 200.
Put 8 as the next digit of the answer. 
Result so far: 308.0
Deduct 3176 from 3376 and we're left with 200.
Fetch the next digit (1) from the dividend, attach it to 200 and continue: 2001 / 397

Step 7:
If we divide 2001 by 397, we get 5 and a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 3085.0
If we take 1985 away from 2001, we end up with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 397

Going ahead to step 8:
397 goes into 160 0 times with a remainder of 160.
The next digit of our result is 0. 
Result so far: 30850.0
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
The number 397 fits into 1600 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 30850.4
Subtract 1588 from 1600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
When dividing 120 by 397, we get 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 30850.4
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
When dividing 1200 by 397, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 30850.403
Subtract 1191 from 1200 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
397 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 30850.403
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 13:
900 divided by 397 is 2 with a remainder of 106.
Use 2 as the next digit of our solution. 
Result so far: 30850.40302
If we take 794 away from 900, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 14:
1060 divided by 397 is 2 with a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 30850.403022
If we subtract 794 from 1060, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The final outcome is 30850.403022, with a leftover of 2.66e-05.
