10491508 ÷ 409 
Let's see how many times 409 fits into 10491508.

Advancing to step 1:
If we divide 1 by 409, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 409

Going ahead to step 2:
409 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 409

Let's proceed to step 3:
When dividing 104 by 409, we get 0 with a remainder of 104.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 104 leaves us with 104.
Append the next digit (9) from the dividend to 104 and continue with: 1049 / 409

Advancing to step 4:
When dividing 1049 by 409, we get 2 with a remainder of 231.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 818 from 1049, we get 231.
Append the next digit (1) from the dividend to 231 and continue with: 2311 / 409

Advancing to step 5:
When dividing 2311 by 409, we get 5 with a remainder of 266.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 2045 from 2311 leaves us with 266.
Take the next digit (5) from the dividend and append it to 266, then repeat: 2665 / 409

On to step 6:
409 can be fit into 2665 6 times, resulting in a remainder of 211.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
Subtract 2454 from 2665 to get 211.
Fetch the next digit (0) from the dividend, attach it to 211 and continue: 2110 / 409

On to step 7:
The number 409 fits into 2110 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 2565.0
Subtract 2045 from 2110 to get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 409

On to step 8:
658 divided by 409 is 1 with a remainder of 249.
Record the quotient 1 as the next digit in the result. 
Result so far: 25651.0
The remainder is 249 after subtracting 409 from 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 9:
The number 409 fits into 2490 6 times, leaving a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 25651.6
If we subtract 2454 from 2490, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
If we divide 360 by 409, we get 0 and a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 25651.6
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 11:
The number 409 fits into 3600 8 times, leaving a remainder of 328.
Write down 8 as next digit of the result. 
Result so far: 25651.608
Deduct 3272 from 3600 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 12:
409 can be fit into 3280 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 25651.6088
Subtracting 3272 from 3280 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 25651.6088, and the remainder is 8e-05.
