91303130 ÷ 409 
Our goal is to divide 91303130 by 409.

Going ahead to step 1:
409 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 409

Moving on to step 2:
91 divided by 409 is 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 409

On to step 3:
If we divide 913 by 409, we get 2 and a remainder of 95.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 818 from 913, we get 95.
Grab the next digit (0) from the dividend, add it to 95, then carry on: 950 / 409

Going ahead to step 4:
If we divide 950 by 409, we get 2 and a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 818 from 950 to get 132.
Append the next digit (3) from the dividend to 132 and continue with: 1323 / 409

Going ahead to step 5:
1323 divided by 409 is 3 with a remainder of 96.
The number 3 becomes the next digit in our result. 
Result so far: 223.0
Subtract 1227 from 1323 to get 96.
Include the next digit (1) from the dividend after 96, then repeat: 961 / 409

Going ahead to step 6:
If we divide 961 by 409, we get 2 and a remainder of 143.
Use 2 as the next digit of our solution. 
Result so far: 2232.0
Deduct 818 from 961 and we're left with 143.
Append the next digit (3) from the dividend to 143 and continue with: 1433 / 409

Going ahead to step 7:
409 goes into 1433 3 times with a remainder of 206.
Write down 3 as next digit of the result. 
Result so far: 22323.0
Subtracting 1227 from 1433 leaves us with 206.
Take the next digit (0) from the dividend and append it to 206, then repeat: 2060 / 409

Going ahead to step 8:
When dividing 2060 by 409, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 223235.0
Deduct 2045 from 2060 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
If we divide 150 by 409, we get 0 and a remainder of 150.
The next digit of our result is 0. 
Result so far: 223235.0
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
409 can be fit into 1500 3 times, resulting in a remainder of 273.
The number 3 becomes the next digit in our result. 
Result so far: 223235.03
The remainder is 273 after subtracting 1227 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 11:
409 can be fit into 2730 6 times, resulting in a remainder of 276.
The next digit of our result is 6. 
Result so far: 223235.036
Subtracting 2454 from 2730 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 12:
When dividing 2760 by 409, we get 6 with a remainder of 306.
Record the quotient 6 as the next digit in the result. 
Result so far: 223235.0366
Subtracting 2454 from 2760 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The final result is 223235.0366 with a remainder of 0.00306.
