We're dividing 19954280 by 409 
We want to figure out the number of times 19954280 can be divided by 409.

Step 1:
If we divide 1 by 409, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 409

Let's proceed to step 2:
19 divided by 409 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 409

Let's proceed to step 3:
199 divided by 409 is 0 with a remainder of 199.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 199 and we're left with 199.
Take the next digit (5) from the dividend and append it to 199, then repeat: 1995 / 409

Advancing to step 4:
When dividing 1995 by 409, we get 4 with a remainder of 359.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 359 after subtracting 1636 from 1995.
Grab the next digit (4) from the dividend, add it to 359, then carry on: 3594 / 409

Step 5:
409 can be fit into 3594 8 times, resulting in a remainder of 322.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 3272 from 3594 to get 322.
Fetch the next digit (2) from the dividend, attach it to 322 and continue: 3222 / 409

Going ahead to step 6:
3222 divided by 409 is 7 with a remainder of 359.
The next digit of our result is 7. 
Result so far: 487.0
Subtract 2863 from 3222 to get 359.
Include the next digit (8) from the dividend after 359, then repeat: 3598 / 409

Moving on to step 7:
The number 409 fits into 3598 8 times, leaving a remainder of 326.
Write down 8 as next digit of the result. 
Result so far: 4878.0
Deduct 3272 from 3598 and we're left with 326.
Take the next digit (0) from the dividend and append it to 326, then repeat: 3260 / 409

Advancing to step 8:
409 can be fit into 3260 7 times, resulting in a remainder of 397.
Use 7 as the next digit of our solution. 
Result so far: 48787.0
Subtracting 2863 from 3260 leaves us with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Going ahead to step 9:
3970 divided by 409 is 9 with a remainder of 289.
Use 9 as the next digit of our solution. 
Result so far: 48787.9
Subtracting 3681 from 3970 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 10:
If we divide 2890 by 409, we get 7 and a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 48787.97
If we subtract 2863 from 2890, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
270 divided by 409 is 0 with a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 48787.97
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 12:
409 goes into 2700 6 times with a remainder of 246.
Use 6 as the next digit of our solution. 
Result so far: 48787.9706
If we subtract 2454 from 2700, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 13:
2460 divided by 409 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 48787.97066
Deduct 2454 from 2460 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 48787.97066 with a remaining 6e-06.
