We're dividing 19109663 by 409 
Let's see how many times 409 fits into 19109663.

Advancing to step 1:
1 divided by 409 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 409

Going ahead to step 2:
The number 409 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 409

Going ahead to step 3:
If we divide 191 by 409, we get 0 and a remainder of 191.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 191 to get 191.
Include the next digit (0) from the dividend after 191, then repeat: 1910 / 409

Moving on to step 4:
1910 divided by 409 is 4 with a remainder of 274.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1636 from 1910 and we're left with 274.
Include the next digit (9) from the dividend after 274, then repeat: 2749 / 409

Going ahead to step 5:
409 goes into 2749 6 times with a remainder of 295.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we take 2454 away from 2749, we end up with 295.
Bring next digit (6) of the dividend behind the 295 and repeat the process: 2956 / 409

Let's proceed to step 6:
409 goes into 2956 7 times with a remainder of 93.
The next digit of our result is 7. 
Result so far: 467.0
If we take 2863 away from 2956, we end up with 93.
Grab the next digit (6) from the dividend, add it to 93, then carry on: 936 / 409

Let's proceed to step 7:
409 can be fit into 936 2 times, resulting in a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 4672.0
If we take 818 away from 936, we end up with 118.
Append the next digit (3) from the dividend to 118 and continue with: 1183 / 409

Step 8:
1183 divided by 409 is 2 with a remainder of 365.
Use 2 as the next digit of our solution. 
Result so far: 46722.0
Subtracting 818 from 1183 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 9:
When dividing 3650 by 409, we get 8 with a remainder of 378.
Put 8 as the next digit of the answer. 
Result so far: 46722.8
The remainder is 378 after subtracting 3272 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 10:
3780 divided by 409 is 9 with a remainder of 99.
Record the quotient 9 as the next digit in the result. 
Result so far: 46722.89
If we take 3681 away from 3780, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 11:
990 divided by 409 is 2 with a remainder of 172.
The next digit of our result is 2. 
Result so far: 46722.892
The remainder is 172 after subtracting 818 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 12:
1720 divided by 409 is 4 with a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 46722.8924
The remainder is 84 after subtracting 1636 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 13:
409 can be fit into 840 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 46722.89242
The remainder is 22 after subtracting 818 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
409 goes into 220 0 times with a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 46722.89242
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 15:
When dividing 2200 by 409, we get 5 with a remainder of 155.
The next digit of our result is 5. 
Result so far: 46722.8924205
Subtracting 2045 from 2200 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 16:
When dividing 1550 by 409, we get 3 with a remainder of 323.
Put 3 as the next digit of the answer. 
Result so far: 46722.89242053
Subtracting 1227 from 1550 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

After the division, we end up with 46722.89242053 and a remainder of 3.23e-07.
