We're dividing 23406778 by 449 
We want to figure out the number of times 23406778 can be divided by 449.

Step 1:
2 divided by 449 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 449

Advancing to step 2:
The number 449 fits into 23 0 times, leaving a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 449

Advancing to step 3:
234 divided by 449 is 0 with a remainder of 234.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 234, we end up with 234.
Grab the next digit (0) from the dividend, add it to 234, then carry on: 2340 / 449

Let's proceed to step 4:
2340 divided by 449 is 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 2245 from 2340 to get 95.
Include the next digit (6) from the dividend after 95, then repeat: 956 / 449

Going ahead to step 5:
956 divided by 449 is 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 52.0
Subtracting 898 from 956 leaves us with 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 449

Going ahead to step 6:
449 goes into 587 1 times with a remainder of 138.
Write down 1 as next digit of the result. 
Result so far: 521.0
Subtract 449 from 587 to get 138.
Append the next digit (7) from the dividend to 138 and continue with: 1387 / 449

Going ahead to step 7:
1387 divided by 449 is 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 5213.0
Deduct 1347 from 1387 and we're left with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 449

Advancing to step 8:
If we divide 408 by 449, we get 0 and a remainder of 408.
The number 0 becomes the next digit in our result. 
Result so far: 52130.0
Subtracting 0 from 408 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 9:
The number 449 fits into 4080 9 times, leaving a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 52130.9
If we subtract 4041 from 4080, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
449 can be fit into 390 0 times, resulting in a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 52130.9
Deduct 0 from 390 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 11:
If we divide 3900 by 449, we get 8 and a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 52130.908
Deduct 3592 from 3900 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 12:
The number 449 fits into 3080 6 times, leaving a remainder of 386.
Put 6 as the next digit of the answer. 
Result so far: 52130.9086
Deduct 2694 from 3080 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 13:
449 can be fit into 3860 8 times, resulting in a remainder of 268.
The next digit of our result is 8. 
Result so far: 52130.90868
Subtracting 3592 from 3860 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 14:
If we divide 2680 by 449, we get 5 and a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 52130.908685
Subtracting 2245 from 2680 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Going ahead to step 15:
If we divide 4350 by 449, we get 9 and a remainder of 309.
The next digit of our result is 9. 
Result so far: 52130.9086859
If we subtract 4041 from 4350, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 16:
The number 449 fits into 3090 6 times, leaving a remainder of 396.
Use 6 as the next digit of our solution. 
Result so far: 52130.90868596
Subtracting 2694 from 3090 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The final result is 52130.90868596 with a remainder of 3.96e-07.
