85440407 ÷ 909 
We're looking to find how many times 909 goes into 85440407.

Moving on to step 1:
When dividing 8 by 909, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 909

On to step 2:
The number 909 fits into 85 0 times, leaving a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Append the next digit (4) from the dividend to 85 and continue with: 854 / 909

Going ahead to step 3:
854 divided by 909 is 0 with a remainder of 854.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 854 to get 854.
Take the next digit (4) from the dividend and append it to 854, then repeat: 8544 / 909

On to step 4:
The number 909 fits into 8544 9 times, leaving a remainder of 363.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 8181 from 8544 and we're left with 363.
Fetch the next digit (0) from the dividend, attach it to 363 and continue: 3630 / 909

On to step 5:
3630 divided by 909 is 3 with a remainder of 903.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtracting 2727 from 3630 leaves us with 903.
Take the next digit (4) from the dividend and append it to 903, then repeat: 9034 / 909

Let's proceed to step 6:
909 can be fit into 9034 9 times, resulting in a remainder of 853.
Write down 9 as next digit of the result. 
Result so far: 939.0
Deduct 8181 from 9034 and we're left with 853.
Append the next digit (0) from the dividend to 853 and continue with: 8530 / 909

Let's proceed to step 7:
If we divide 8530 by 909, we get 9 and a remainder of 349.
Use 9 as the next digit of our solution. 
Result so far: 9399.0
Subtract 8181 from 8530 to get 349.
Bring next digit (7) of the dividend behind the 349 and repeat the process: 3497 / 909

Moving on to step 8:
909 can be fit into 3497 3 times, resulting in a remainder of 770.
Put 3 as the next digit of the answer. 
Result so far: 93993.0
Subtracting 2727 from 3497 leaves us with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 9:
If we divide 7700 by 909, we get 8 and a remainder of 428.
Record the quotient 8 as the next digit in the result. 
Result so far: 93993.8
The remainder is 428 after subtracting 7272 from 7700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 10:
When dividing 4280 by 909, we get 4 with a remainder of 644.
Write down 4 as next digit of the result. 
Result so far: 93993.84
Subtract 3636 from 4280 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 11:
909 goes into 6440 7 times with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 93993.847
If we take 6363 away from 6440, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 12:
The number 909 fits into 770 0 times, leaving a remainder of 770.
Put 0 as the next digit of the answer. 
Result so far: 93993.847
Subtract 0 from 770 to get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 13:
909 goes into 7700 8 times with a remainder of 428.
The next digit of our result is 8. 
Result so far: 93993.84708
Deduct 7272 from 7700 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 14:
4280 divided by 909 is 4 with a remainder of 644.
Record the quotient 4 as the next digit in the result. 
Result so far: 93993.847084
If we subtract 3636 from 4280, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Going ahead to step 15:
The number 909 fits into 6440 7 times, leaving a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 93993.8470847
Subtract 6363 from 6440 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 16:
When dividing 770 by 909, we get 0 with a remainder of 770.
Use 0 as the next digit of our solution. 
Result so far: 93993.8470847
If we take 0 away from 770, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

After the division, we end up with 93993.8470847 and a remainder of 7.7e-07.
