Let's divide 87390656 by 909
Our goal is to divide 87390656 by 909.

On to step 1:
If we divide 8 by 909, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 909

Step 2:
909 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (3) from the dividend, attach it to 87 and continue: 873 / 909

Moving on to step 3:
When dividing 873 by 909, we get 0 with a remainder of 873.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 873, we get 873.
Append the next digit (9) from the dividend to 873 and continue with: 8739 / 909

Going ahead to step 4:
When dividing 8739 by 909, we get 9 with a remainder of 558.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 8181 from 8739 leaves us with 558.
Include the next digit (0) from the dividend after 558, then repeat: 5580 / 909

Moving on to step 5:
5580 divided by 909 is 6 with a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Deduct 5454 from 5580 and we're left with 126.
Append the next digit (6) from the dividend to 126 and continue with: 1266 / 909

Step 6:
1266 divided by 909 is 1 with a remainder of 357.
Put 1 as the next digit of the answer. 
Result so far: 961.0
Subtract 909 from 1266 to get 357.
Fetch the next digit (5) from the dividend, attach it to 357 and continue: 3575 / 909

On to step 7:
The number 909 fits into 3575 3 times, leaving a remainder of 848.
Use 3 as the next digit of our solution. 
Result so far: 9613.0
Subtract 2727 from 3575 to get 848.
Bring next digit (6) of the dividend behind the 848 and repeat the process: 8486 / 909

Moving on to step 8:
When dividing 8486 by 909, we get 9 with a remainder of 305.
Record the quotient 9 as the next digit in the result. 
Result so far: 96139.0
Deduct 8181 from 8486 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 9:
The number 909 fits into 3050 3 times, leaving a remainder of 323.
Put 3 as the next digit of the answer. 
Result so far: 96139.3
Subtract 2727 from 3050 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 10:
909 goes into 3230 3 times with a remainder of 503.
Write down 3 as next digit of the result. 
Result so far: 96139.33
If we take 2727 away from 3230, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

The quotient of the division is 96139.33, and the remainder is 0.503.
