68490908 divided by 449 
We're looking to find how many times 449 goes into 68490908.

Moving on to step 1:
6 divided by 449 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 449

On to step 2:
68 divided by 449 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 449

Moving on to step 3:
449 can be fit into 684 1 times, resulting in a remainder of 235.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 449 from 684 and we're left with 235.
Bring next digit (9) of the dividend behind the 235 and repeat the process: 2359 / 449

On to step 4:
If we divide 2359 by 449, we get 5 and a remainder of 114.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2245 away from 2359, we end up with 114.
Fetch the next digit (0) from the dividend, attach it to 114 and continue: 1140 / 449

Let's proceed to step 5:
449 can be fit into 1140 2 times, resulting in a remainder of 242.
The next digit of our result is 2. 
Result so far: 152.0
If we subtract 898 from 1140, we get 242.
Fetch the next digit (9) from the dividend, attach it to 242 and continue: 2429 / 449

Moving on to step 6:
449 can be fit into 2429 5 times, resulting in a remainder of 184.
The next digit of our result is 5. 
Result so far: 1525.0
Deduct 2245 from 2429 and we're left with 184.
Append the next digit (0) from the dividend to 184 and continue with: 1840 / 449

Moving on to step 7:
1840 divided by 449 is 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 15254.0
Subtract 1796 from 1840 to get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 449

On to step 8:
449 can be fit into 448 0 times, resulting in a remainder of 448.
The next digit of our result is 0. 
Result so far: 152540.0
Subtracting 0 from 448 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 9:
If we divide 4480 by 449, we get 9 and a remainder of 439.
Write down 9 as next digit of the result. 
Result so far: 152540.9
Deduct 4041 from 4480 and we're left with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 10:
If we divide 4390 by 449, we get 9 and a remainder of 349.
The next digit of our result is 9. 
Result so far: 152540.99
Subtracting 4041 from 4390 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

The final outcome is 152540.99, with a leftover of 0.349.
