68231149 ÷ 909 
Our goal is to divide 68231149 by 909.

Step 1:
The number 909 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 909

Moving on to 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
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 909

Step 3:
682 divided by 909 is 0 with a remainder of 682.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 682 after subtracting 0 from 682.
Grab the next digit (3) from the dividend, add it to 682, then carry on: 6823 / 909

On to step 4:
The number 909 fits into 6823 7 times, leaving a remainder of 460.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 460 after subtracting 6363 from 6823.
Bring next digit (1) of the dividend behind the 460 and repeat the process: 4601 / 909

Advancing to step 5:
909 goes into 4601 5 times with a remainder of 56.
The next digit of our result is 5. 
Result so far: 75.0
If we take 4545 away from 4601, we end up with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 909

Let's proceed to step 6:
When dividing 561 by 909, we get 0 with a remainder of 561.
Put 0 as the next digit of the answer. 
Result so far: 750.0
If we take 0 away from 561, we end up with 561.
Take the next digit (4) from the dividend and append it to 561, then repeat: 5614 / 909

Going ahead to step 7:
909 can be fit into 5614 6 times, resulting in a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 7506.0
If we subtract 5454 from 5614, we get 160.
Bring next digit (9) of the dividend behind the 160 and repeat the process: 1609 / 909

Let's proceed to step 8:
When dividing 1609 by 909, we get 1 with a remainder of 700.
The next digit of our result is 1. 
Result so far: 75061.0
Deduct 909 from 1609 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 9:
When dividing 7000 by 909, we get 7 with a remainder of 637.
Record the quotient 7 as the next digit in the result. 
Result so far: 75061.7
Deduct 6363 from 7000 and we're left with 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Moving on to step 10:
909 goes into 6370 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 75061.77
Deduct 6363 from 6370 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 75061.77 with a remainder of 0.007.
