We look at the division of 28972880 by 409 
We're looking to find how many times 409 goes into 28972880.

Advancing to step 1:
The number 409 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 409

Advancing to step 2:
If we divide 28 by 409, we get 0 and a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 409

Advancing to step 3:
If we divide 289 by 409, we get 0 and a remainder of 289.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 289 leaves us with 289.
Fetch the next digit (7) from the dividend, attach it to 289 and continue: 2897 / 409

Step 4:
409 can be fit into 2897 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 2863 from 2897 leaves us with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 409

Step 5:
The number 409 fits into 342 0 times, leaving a remainder of 342.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 342 leaves us with 342.
Bring next digit (8) of the dividend behind the 342 and repeat the process: 3428 / 409

Let's proceed to step 6:
409 goes into 3428 8 times with a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 708.0
If we subtract 3272 from 3428, we get 156.
Append the next digit (8) from the dividend to 156 and continue with: 1568 / 409

Going ahead to step 7:
The number 409 fits into 1568 3 times, leaving a remainder of 341.
Record the quotient 3 as the next digit in the result. 
Result so far: 7083.0
If we subtract 1227 from 1568, we get 341.
Fetch the next digit (0) from the dividend, attach it to 341 and continue: 3410 / 409

Let's proceed to step 8:
When dividing 3410 by 409, we get 8 with a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 70838.0
If we take 3272 away from 3410, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 9:
When dividing 1380 by 409, we get 3 with a remainder of 153.
Record the quotient 3 as the next digit in the result. 
Result so far: 70838.3
Deduct 1227 from 1380 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 10:
1530 divided by 409 is 3 with a remainder of 303.
The next digit of our result is 3. 
Result so far: 70838.33
If we subtract 1227 from 1530, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

The final outcome is 70838.33, with a leftover of 0.303.
