If we divide 6 by 909, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 909

Step 2:
68 divided by 909 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Bring next digit (5) of the dividend behind the 68 and repeat the process: 685 / 909

On to step 3:
If we divide 685 by 909, we get 0 and a remainder of 685.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 685 and we're left with 685.
Grab the next digit (7) from the dividend, add it to 685, then carry on: 6857 / 909

Going ahead to step 4:
909 can be fit into 6857 7 times, resulting in a remainder of 494.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 6363 from 6857 and we're left with 494.
Append the next digit (4) from the dividend to 494 and continue with: 4944 / 909

On to step 5:
If we divide 4944 by 909, we get 5 and a remainder of 399.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we subtract 4545 from 4944, we get 399.
Fetch the next digit (0) from the dividend, attach it to 399 and continue: 3990 / 909

Advancing to step 6:
The number 909 fits into 3990 4 times, leaving a remainder of 354.
Record the quotient 4 as the next digit in the result. 
Result so far: 754.0
The remainder is 354 after subtracting 3636 from 3990.
Bring next digit (2) of the dividend behind the 354 and repeat the process: 3542 / 909

Let's proceed to step 7:
The number 909 fits into 3542 3 times, leaving a remainder of 815.
Use 3 as the next digit of our solution. 
Result so far: 7543.0
The remainder is 815 after subtracting 2727 from 3542.
Bring next digit (4) of the dividend behind the 815 and repeat the process: 8154 / 909

On to step 8:
909 can be fit into 8154 8 times, resulting in a remainder of 882.
Put 8 as the next digit of the answer. 
Result so far: 75438.0
If we subtract 7272 from 8154, we get 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Advancing to step 9:
When dividing 8820 by 909, we get 9 with a remainder of 639.
Put 9 as the next digit of the answer. 
Result so far: 75438.9
Deduct 8181 from 8820 and we're left with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Step 10:
909 can be fit into 6390 7 times, resulting in a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 75438.97
If we take 6363 away from 6390, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
909 can be fit into 270 0 times, resulting in a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 75438.97
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 12:
909 can be fit into 2700 2 times, resulting in a remainder of 882.
The number 2 becomes the next digit in our result. 
Result so far: 75438.9702
If we subtract 1818 from 2700, we get 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Moving on to step 13:
8820 divided by 909 is 9 with a remainder of 639.
The next digit of our result is 9. 
Result so far: 75438.97029
Deduct 8181 from 8820 and we're left with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Going ahead to step 14:
The number 909 fits into 6390 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 75438.970297
The remainder is 27 after subtracting 6363 from 6390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 15:
909 goes into 270 0 times with a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 75438.970297
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 16:
When dividing 2700 by 909, we get 2 with a remainder of 882.
Record the quotient 2 as the next digit in the result. 
Result so far: 75438.97029702
Deduct 1818 from 2700 and we're left with 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

The final result is 75438.97029702 with a remainder of 8.82e-07.
