407454 divided by 28 
We want to figure out the number of times 407454 can be divided by 28.

Step 1:
28 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 28

Moving on to step 2:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 12 after subtracting 28 from 40.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 28

Let's proceed to step 3:
127 divided by 28 is 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 112 away from 127, we end up with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 28

Let's proceed to step 4:
When dividing 154 by 28, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 145.0
Subtracting 140 from 154 leaves us with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 28

Moving on to step 5:
28 goes into 145 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1455.0
If we take 140 away from 145, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 28

Step 6:
54 divided by 28 is 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 14551.0
Deduct 28 from 54 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
260 divided by 28 is 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 14551.9
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 14551.92
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
28 goes into 240 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 14551.928
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 14551.9285
Subtract 140 from 160 to get 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:
If we divide 200 by 28, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 14551.92857
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
If we divide 40 by 28, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 14551.928571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 14551.9285714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 14551.92857142
If we take 56 away from 80, we end up 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.

The final result is 14551.92857142 with a remainder of 2.4e-08.
