We look at the division of 15198241 by 409 
We want to divide 15198241 by 409.

On to step 1:
When dividing 1 by 409, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 409

Let's proceed to step 2:
The number 409 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 409

Going ahead to step 3:
The number 409 fits into 151 0 times, leaving a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 151, we end up with 151.
Include the next digit (9) from the dividend after 151, then repeat: 1519 / 409

Advancing to step 4:
When dividing 1519 by 409, we get 3 with a remainder of 292.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1227 from 1519 to get 292.
Bring next digit (8) of the dividend behind the 292 and repeat the process: 2928 / 409

Going ahead to step 5:
When dividing 2928 by 409, we get 7 with a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtracting 2863 from 2928 leaves us with 65.
Take the next digit (2) from the dividend and append it to 65, then repeat: 652 / 409

On to step 6:
409 can be fit into 652 1 times, resulting in a remainder of 243.
Use 1 as the next digit of our solution. 
Result so far: 371.0
If we subtract 409 from 652, we get 243.
Bring next digit (4) of the dividend behind the 243 and repeat the process: 2434 / 409

On to step 7:
409 can be fit into 2434 5 times, resulting in a remainder of 389.
Use 5 as the next digit of our solution. 
Result so far: 3715.0
If we subtract 2045 from 2434, we get 389.
Bring next digit (1) of the dividend behind the 389 and repeat the process: 3891 / 409

Going ahead to step 8:
When dividing 3891 by 409, we get 9 with a remainder of 210.
Put 9 as the next digit of the answer. 
Result so far: 37159.0
Deduct 3681 from 3891 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 9:
2100 divided by 409 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 37159.5
If we take 2045 away from 2100, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
409 can be fit into 550 1 times, resulting in a remainder of 141.
Record the quotient 1 as the next digit in the result. 
Result so far: 37159.51
Subtract 409 from 550 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 11:
When dividing 1410 by 409, we get 3 with a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 37159.513
Subtract 1227 from 1410 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 12:
The number 409 fits into 1830 4 times, leaving a remainder of 194.
Use 4 as the next digit of our solution. 
Result so far: 37159.5134
Deduct 1636 from 1830 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 13:
409 can be fit into 1940 4 times, resulting in a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 37159.51344
Subtract 1636 from 1940 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final outcome is 37159.51344, with a leftover of 0.000304.
