405574 ÷ 28 
We want to figure out the number of times 405574 can be divided by 28.

Step 1:
28 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 28

On to step 2:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 28 from 40 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 28

Step 3:
If we divide 125 by 28, we get 4 and a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 112 away from 125, we end up with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 28

Step 4:
When dividing 135 by 28, we get 4 with a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 144.0
The remainder is 23 after subtracting 112 from 135.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 28

On to step 5:
If we divide 237 by 28, we get 8 and a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 1448.0
Subtract 224 from 237 to get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 28

Moving on to step 6:
28 goes into 134 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 14484.0
If we take 112 away from 134, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
When dividing 220 by 28, we get 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 14484.7
If we subtract 196 from 220, we 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.

Step 8:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 14484.78
The remainder is 16 after subtracting 224 from 240.
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 9:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 14484.785
If we take 140 away from 160, we end up 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.

Advancing to step 10:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 14484.7857
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 11:
If we divide 40 by 28, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 14484.78571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 28, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 14484.785714
Subtract 112 from 120 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 13:
28 goes into 80 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 14484.7857142
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.

Advancing to step 14:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 14484.78571428
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.

After the division, we end up with 14484.78571428 and a remainder of 1.6e-08.
