12505299 divided by 404 
We're looking to find how many times 404 goes into 12505299.

Going ahead to step 1:
404 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 404

Going ahead to step 2:
If we divide 12 by 404, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 404

Advancing to step 3:
404 can be fit into 125 0 times, resulting in a remainder of 125.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 125 to get 125.
Include the next digit (0) from the dividend after 125, then repeat: 1250 / 404

Let's proceed to step 4:
404 can be fit into 1250 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1212 away from 1250, we end up with 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 404

Advancing to step 5:
When dividing 385 by 404, we get 0 with a remainder of 385.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 385 after subtracting 0 from 385.
Append the next digit (2) from the dividend to 385 and continue with: 3852 / 404

On to step 6:
When dividing 3852 by 404, we get 9 with a remainder of 216.
Put 9 as the next digit of the answer. 
Result so far: 309.0
If we take 3636 away from 3852, we end up with 216.
Include the next digit (9) from the dividend after 216, then repeat: 2169 / 404

Let's proceed to step 7:
2169 divided by 404 is 5 with a remainder of 149.
Use 5 as the next digit of our solution. 
Result so far: 3095.0
Deduct 2020 from 2169 and we're left with 149.
Grab the next digit (9) from the dividend, add it to 149, then carry on: 1499 / 404

Going ahead to step 8:
When dividing 1499 by 404, we get 3 with a remainder of 287.
Use 3 as the next digit of our solution. 
Result so far: 30953.0
If we take 1212 away from 1499, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 9:
If we divide 2870 by 404, we get 7 and a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 30953.7
The remainder is 42 after subtracting 2828 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
404 goes into 420 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 30953.71
Subtracting 404 from 420 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
If we divide 160 by 404, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 30953.71
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
When dividing 1600 by 404, we get 3 with a remainder of 388.
The next digit of our result is 3. 
Result so far: 30953.7103
Deduct 1212 from 1600 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 13:
404 can be fit into 3880 9 times, resulting in a remainder of 244.
The next digit of our result is 9. 
Result so far: 30953.71039
Subtract 3636 from 3880 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 14:
If we divide 2440 by 404, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 30953.710396
If we subtract 2424 from 2440, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 15:
When dividing 160 by 404, we get 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 30953.710396
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
The number 404 fits into 1600 3 times, leaving a remainder of 388.
Use 3 as the next digit of our solution. 
Result so far: 30953.71039603
If we subtract 1212 from 1600, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final outcome is 30953.71039603, with a leftover of 3.88e-07.
