Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 909

Moving on to step 2:
33 divided by 909 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 909

Going ahead to step 3:
The number 909 fits into 331 0 times, leaving a remainder of 331.
The number 0 becomes the next digit in our result. 
Result so far: 0.0

Fetch the next digit (3) from the dividend, attach it to 331 and continue: 3313 / 909

Advancing to step 4:
When dividing 3313 by 909, we get 3 with a remainder of 586.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 2727 from 3313 leaves us with 586.
Fetch the next digit (8) from the dividend, attach it to 586 and continue: 5868 / 909

Advancing to step 5:
909 can be fit into 5868 6 times, resulting in a remainder of 414.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtract 5454 from 5868 to get 414.
Append the next digit (3) from the dividend to 414 and continue with: 4143 / 909

Advancing to step 6:
909 goes into 4143 4 times with a remainder of 507.
Use 4 as the next digit of our solution. 
Result so far: 364.0
The remainder is 507 after subtracting 3636 from 4143.
Fetch the next digit (9) from the dividend, attach it to 507 and continue: 5079 / 909

Moving on to step 7:
When dividing 5079 by 909, we get 5 with a remainder of 534.
Use 5 as the next digit of our solution. 
Result so far: 3645.0
Subtracting 4545 from 5079 leaves us with 534.
Grab the next digit (1) from the dividend, add it to 534, then carry on: 5341 / 909

Going ahead to step 8:
If we divide 5341 by 909, we get 5 and a remainder of 796.
Use 5 as the next digit of our solution. 
Result so far: 36455.0
Subtracting 4545 from 5341 leaves us with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Advancing to step 9:
If we divide 7960 by 909, we get 8 and a remainder of 688.
Put 8 as the next digit of the answer. 
Result so far: 36455.8
If we subtract 7272 from 7960, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 10:
6880 divided by 909 is 7 with a remainder of 517.
Write down 7 as next digit of the result. 
Result so far: 36455.87
The remainder is 517 after subtracting 6363 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Going ahead to step 11:
909 can be fit into 5170 5 times, resulting in a remainder of 625.
Put 5 as the next digit of the answer. 
Result so far: 36455.875
If we subtract 4545 from 5170, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 12:
If we divide 6250 by 909, we get 6 and a remainder of 796.
Put 6 as the next digit of the answer. 
Result so far: 36455.8756
Subtracting 5454 from 6250 leaves us with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Advancing to step 13:
The number 909 fits into 7960 8 times, leaving a remainder of 688.
Write down 8 as next digit of the result. 
Result so far: 36455.87568
Deduct 7272 from 7960 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 14:
909 goes into 6880 7 times with a remainder of 517.
The next digit of our result is 7. 
Result so far: 36455.875687
Subtracting 6363 from 6880 leaves us with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Step 15:
The number 909 fits into 5170 5 times, leaving a remainder of 625.
Use 5 as the next digit of our solution. 
Result so far: 36455.8756875
Subtract 4545 from 5170 to get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 16:
When dividing 6250 by 909, we get 6 with a remainder of 796.
The number 6 becomes the next digit in our result. 
Result so far: 36455.87568756
Subtract 5454 from 6250 to get 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

The final outcome is 36455.87568756, with a leftover of 7.96e-07.
