12599794 divided by 406 
Let's see how many times 406 fits into 12599794.

Going ahead to step 1:
406 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 406

On to step 2:
406 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 406

Step 3:
406 can be fit into 125 0 times, resulting in a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 125 after subtracting 0 from 125.
Append the next digit (9) from the dividend to 125 and continue with: 1259 / 406

Let's proceed to step 4:
406 can be fit into 1259 3 times, resulting in a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1218 away from 1259, we end up with 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 406

Going ahead to step 5:
When dividing 419 by 406, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 406 from 419 and we're left with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 406

Advancing to step 6:
The number 406 fits into 137 0 times, leaving a remainder of 137.
Write down 0 as next digit of the result. 
Result so far: 310.0
Deduct 0 from 137 and we're left with 137.
Bring next digit (9) of the dividend behind the 137 and repeat the process: 1379 / 406

Going ahead to step 7:
1379 divided by 406 is 3 with a remainder of 161.
Record the quotient 3 as the next digit in the result. 
Result so far: 3103.0
The remainder is 161 after subtracting 1218 from 1379.
Take the next digit (4) from the dividend and append it to 161, then repeat: 1614 / 406

Step 8:
406 can be fit into 1614 3 times, resulting in a remainder of 396.
Use 3 as the next digit of our solution. 
Result so far: 31033.0
Subtract 1218 from 1614 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 9:
406 can be fit into 3960 9 times, resulting in a remainder of 306.
Put 9 as the next digit of the answer. 
Result so far: 31033.9
Subtracting 3654 from 3960 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 10:
406 can be fit into 3060 7 times, resulting in a remainder of 218.
The number 7 becomes the next digit in our result. 
Result so far: 31033.97
If we subtract 2842 from 3060, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 11:
If we divide 2180 by 406, we get 5 and a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 31033.975
The remainder is 150 after subtracting 2030 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
The number 406 fits into 1500 3 times, leaving a remainder of 282.
The number 3 becomes the next digit in our result. 
Result so far: 31033.9753
If we take 1218 away from 1500, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 13:
The number 406 fits into 2820 6 times, leaving a remainder of 384.
The next digit of our result is 6. 
Result so far: 31033.97536
If we take 2436 away from 2820, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 14:
The number 406 fits into 3840 9 times, leaving a remainder of 186.
The number 9 becomes the next digit in our result. 
Result so far: 31033.975369
Deduct 3654 from 3840 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 15:
406 goes into 1860 4 times with a remainder of 236.
Put 4 as the next digit of the answer. 
Result so far: 31033.9753694
If we take 1624 away from 1860, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 16:
406 goes into 2360 5 times with a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 31033.97536945
If we take 2030 away from 2360, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final result is 31033.97536945 with a remainder of 3.3e-07.
