16304146 ÷ 453 
Our goal is to divide 16304146 by 453.

On to step 1:
453 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 453

Going ahead to step 2:
The number 453 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 453

Let's proceed to step 3:
453 goes into 163 0 times with a remainder of 163.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 163 and we're left with 163.
Take the next digit (0) from the dividend and append it to 163, then repeat: 1630 / 453

Let's proceed to step 4:
The number 453 fits into 1630 3 times, leaving a remainder of 271.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1359 from 1630 and we're left with 271.
Take the next digit (4) from the dividend and append it to 271, then repeat: 2714 / 453

Moving on to step 5:
When dividing 2714 by 453, we get 5 with a remainder of 449.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we subtract 2265 from 2714, we get 449.
Bring next digit (1) of the dividend behind the 449 and repeat the process: 4491 / 453

Let's proceed to step 6:
453 can be fit into 4491 9 times, resulting in a remainder of 414.
The number 9 becomes the next digit in our result. 
Result so far: 359.0
The remainder is 414 after subtracting 4077 from 4491.
Take the next digit (4) from the dividend and append it to 414, then repeat: 4144 / 453

Advancing to step 7:
453 can be fit into 4144 9 times, resulting in a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 3599.0
If we subtract 4077 from 4144, we get 67.
Bring next digit (6) of the dividend behind the 67 and repeat the process: 676 / 453

Moving on to step 8:
453 goes into 676 1 times with a remainder of 223.
The number 1 becomes the next digit in our result. 
Result so far: 35991.0
Deduct 453 from 676 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 9:
2230 divided by 453 is 4 with a remainder of 418.
The number 4 becomes the next digit in our result. 
Result so far: 35991.4
The remainder is 418 after subtracting 1812 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 10:
The number 453 fits into 4180 9 times, leaving a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 35991.49
If we take 4077 away from 4180, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 11:
The number 453 fits into 1030 2 times, leaving a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 35991.492
The remainder is 124 after subtracting 906 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 12:
If we divide 1240 by 453, we get 2 and a remainder of 334.
Write down 2 as next digit of the result. 
Result so far: 35991.4922
If we subtract 906 from 1240, 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.

The final outcome is 35991.4922, with a leftover of 0.00334.
