454480 ÷ 28 
We're looking to find how many times 28 goes into 454480.

Let's proceed to step 1:
When dividing 4 by 28, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 28

Step 2:
28 goes into 45 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 28 from 45 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 28

On to step 3:
The number 28 fits into 174 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 168 away from 174, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 28

Moving on to step 4:
64 divided by 28 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 162.0
Subtract 56 from 64 to get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 28

Step 5:
When dividing 88 by 28, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 1623.0
Deduct 84 from 88 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 28

Let's proceed to step 6:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 16231.0
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
If we divide 120 by 28, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 16231.4
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
When dividing 80 by 28, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 16231.42
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
When dividing 240 by 28, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 16231.428
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 16231.4285
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
28 goes into 200 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 16231.42857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
When dividing 40 by 28, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 16231.428571
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 16231.4285714
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 16231.42857142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 16231.42857142, with a leftover of 2.4e-08.
