12298495 ÷ 904 
We want to figure out the number of times 12298495 can be divided by 904.

Let's proceed to step 1:
904 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 904

Step 2:
904 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 904

Let's proceed to step 3:
122 divided by 904 is 0 with a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 122, we get 122.
Grab the next digit (9) from the dividend, add it to 122, then carry on: 1229 / 904

On to step 4:
904 can be fit into 1229 1 times, resulting in a remainder of 325.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 325 after subtracting 904 from 1229.
Bring next digit (8) of the dividend behind the 325 and repeat the process: 3258 / 904

Step 5:
If we divide 3258 by 904, we get 3 and a remainder of 546.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 2712 from 3258 leaves us with 546.
Include the next digit (4) from the dividend after 546, then repeat: 5464 / 904

Step 6:
5464 divided by 904 is 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
Subtract 5424 from 5464 to get 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 904

Let's proceed to step 7:
409 divided by 904 is 0 with a remainder of 409.
Use 0 as the next digit of our solution. 
Result so far: 1360.0
The remainder is 409 after subtracting 0 from 409.
Grab the next digit (5) from the dividend, add it to 409, then carry on: 4095 / 904

Going ahead to step 8:
When dividing 4095 by 904, we get 4 with a remainder of 479.
Put 4 as the next digit of the answer. 
Result so far: 13604.0
If we subtract 3616 from 4095, we get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 9:
904 goes into 4790 5 times with a remainder of 270.
Use 5 as the next digit of our solution. 
Result so far: 13604.5
If we subtract 4520 from 4790, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
If we divide 2700 by 904, we get 2 and a remainder of 892.
Write down 2 as next digit of the result. 
Result so far: 13604.52
The remainder is 892 after subtracting 1808 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Moving on to step 11:
The number 904 fits into 8920 9 times, leaving a remainder of 784.
Use 9 as the next digit of our solution. 
Result so far: 13604.529
The remainder is 784 after subtracting 8136 from 8920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Advancing to step 12:
904 can be fit into 7840 8 times, resulting in a remainder of 608.
Put 8 as the next digit of the answer. 
Result so far: 13604.5298
If we take 7232 away from 7840, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 13:
904 goes into 6080 6 times with a remainder of 656.
Use 6 as the next digit of our solution. 
Result so far: 13604.52986
Deduct 5424 from 6080 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 14:
The number 904 fits into 6560 7 times, leaving a remainder of 232.
Put 7 as the next digit of the answer. 
Result so far: 13604.529867
Subtract 6328 from 6560 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 15:
904 can be fit into 2320 2 times, resulting in a remainder of 512.
The number 2 becomes the next digit in our result. 
Result so far: 13604.5298672
If we subtract 1808 from 2320, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 16:
The number 904 fits into 5120 5 times, leaving a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 13604.52986725
If we subtract 4520 from 5120, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 13604.52986725, and the remainder is 6e-07.
