408690 ÷ 28 
We want to figure out the number of times 408690 can be divided by 28.

Moving on to step 1:
28 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 28

On to step 2:
When dividing 40 by 28, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 28 away from 40, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 28

On to step 3:
The number 28 fits into 128 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 112 from 128 and we're left with 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 28

Moving on to step 4:
When dividing 166 by 28, we get 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 145.0
Subtract 140 from 166 to get 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 28

Step 5:
If we divide 269 by 28, we get 9 and a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 1459.0
Subtract 252 from 269 to get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 28

Let's proceed to step 6:
28 goes into 170 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 14596.0
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 28, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 14596.0
If we subtract 0 from 20, we 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.

Moving on to step 8:
If we divide 200 by 28, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 14596.07
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 14596.071
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.

Moving on to step 10:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 14596.0714
If we subtract 112 from 120, we 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.

Moving on to step 11:
If we divide 80 by 28, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 14596.07142
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.

Going ahead to step 12:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 14596.071428
Deduct 224 from 240 and we're left 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.

On to step 13:
When dividing 160 by 28, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 14596.0714285
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 14:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 14596.07142857
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.

The quotient of the division is 14596.07142857, and the remainder is 4e-09.
