28873565 ÷ 408 
We want to figure out the number of times 28873565 can be divided by 408.

Going ahead to step 1:
408 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 408

Step 2:
The number 408 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 408

Going ahead to step 3:
408 can be fit into 288 0 times, resulting in a remainder of 288.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 288 and we're left with 288.
Take the next digit (7) from the dividend and append it to 288, then repeat: 2887 / 408

Let's proceed to step 4:
When dividing 2887 by 408, we get 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 2856 away from 2887, we end up with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 408

On to step 5:
If we divide 313 by 408, we get 0 and a remainder of 313.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtract 0 from 313 to get 313.
Append the next digit (5) from the dividend to 313 and continue with: 3135 / 408

Moving on to step 6:
408 can be fit into 3135 7 times, resulting in a remainder of 279.
Put 7 as the next digit of the answer. 
Result so far: 707.0
Subtract 2856 from 3135 to get 279.
Append the next digit (6) from the dividend to 279 and continue with: 2796 / 408

Going ahead to step 7:
408 can be fit into 2796 6 times, resulting in a remainder of 348.
Use 6 as the next digit of our solution. 
Result so far: 7076.0
Deduct 2448 from 2796 and we're left with 348.
Grab the next digit (5) from the dividend, add it to 348, then carry on: 3485 / 408

Going ahead to step 8:
408 goes into 3485 8 times with a remainder of 221.
The next digit of our result is 8. 
Result so far: 70768.0
If we subtract 3264 from 3485, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Going ahead to step 9:
408 goes into 2210 5 times with a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 70768.5
Subtract 2040 from 2210 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
When dividing 1700 by 408, we get 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 70768.54
Subtract 1632 from 1700 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
680 divided by 408 is 1 with a remainder of 272.
Put 1 as the next digit of the answer. 
Result so far: 70768.541
The remainder is 272 after subtracting 408 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 12:
If we divide 2720 by 408, we get 6 and a remainder of 272.
The number 6 becomes the next digit in our result. 
Result so far: 70768.5416
If we subtract 2448 from 2720, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 13:
408 can be fit into 2720 6 times, resulting in a remainder of 272.
Use 6 as the next digit of our solution. 
Result so far: 70768.54166
Deduct 2448 from 2720 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final outcome is 70768.54166, with a leftover of 0.000272.
