638204 ÷ 454 
Let's see how many times 454 fits into 638204.

Moving on to step 1:
454 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 454

Let's proceed to step 2:
The number 454 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 454

Going ahead to step 3:
454 can be fit into 638 1 times, resulting in a remainder of 184.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 454 away from 638, we end up with 184.
Append the next digit (2) from the dividend to 184 and continue with: 1842 / 454

Going ahead to step 4:
454 can be fit into 1842 4 times, resulting in a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 1816 from 1842, we get 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 454

Advancing to step 5:
454 can be fit into 260 0 times, resulting in a remainder of 260.
The next digit of our result is 0. 
Result so far: 140.0
The remainder is 260 after subtracting 0 from 260.
Grab the next digit (4) from the dividend, add it to 260, then carry on: 2604 / 454

On to step 6:
The number 454 fits into 2604 5 times, leaving a remainder of 334.
Put 5 as the next digit of the answer. 
Result so far: 1405.0
If we subtract 2270 from 2604, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 7:
454 can be fit into 3340 7 times, resulting in a remainder of 162.
Record the quotient 7 as the next digit in the result. 
Result so far: 1405.7
Subtract 3178 from 3340 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 8:
The number 454 fits into 1620 3 times, leaving a remainder of 258.
Record the quotient 3 as the next digit in the result. 
Result so far: 1405.73
If we take 1362 away from 1620, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 9:
454 can be fit into 2580 5 times, resulting in a remainder of 310.
The next digit of our result is 5. 
Result so far: 1405.735
If we take 2270 away from 2580, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 10:
The number 454 fits into 3100 6 times, leaving a remainder of 376.
The number 6 becomes the next digit in our result. 
Result so far: 1405.7356
Subtracting 2724 from 3100 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 11:
3760 divided by 454 is 8 with a remainder of 128.
The next digit of our result is 8. 
Result so far: 1405.73568
If we subtract 3632 from 3760, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 12:
454 can be fit into 1280 2 times, resulting in a remainder of 372.
The next digit of our result is 2. 
Result so far: 1405.735682
Subtract 908 from 1280 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 13:
454 can be fit into 3720 8 times, resulting in a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 1405.7356828
If we take 3632 away from 3720, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 14:
If we divide 880 by 454, we get 1 and a remainder of 426.
Record the quotient 1 as the next digit in the result. 
Result so far: 1405.73568281
The remainder is 426 after subtracting 454 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

In conclusion, the division gives 1405.73568281 with a balance of 4.26e-07.
