Let's divide 90416909 by 804
We want to divide 90416909 by 804.

Step 1:
When dividing 9 by 804, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 804

Advancing to step 2:
804 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Take the next digit (4) from the dividend and append it to 90, then repeat: 904 / 804

Let's proceed to step 3:
904 divided by 804 is 1 with a remainder of 100.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 804 from 904 to get 100.
Grab the next digit (1) from the dividend, add it to 100, then carry on: 1001 / 804

Advancing to step 4:
1001 divided by 804 is 1 with a remainder of 197.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 804 from 1001 and we're left with 197.
Grab the next digit (6) from the dividend, add it to 197, then carry on: 1976 / 804

On to step 5:
When dividing 1976 by 804, we get 2 with a remainder of 368.
Write down 2 as next digit of the result. 
Result so far: 112.0
The remainder is 368 after subtracting 1608 from 1976.
Include the next digit (9) from the dividend after 368, then repeat: 3689 / 804

Advancing to step 6:
804 goes into 3689 4 times with a remainder of 473.
Write down 4 as next digit of the result. 
Result so far: 1124.0
Subtract 3216 from 3689 to get 473.
Bring next digit (0) of the dividend behind the 473 and repeat the process: 4730 / 804

Step 7:
If we divide 4730 by 804, we get 5 and a remainder of 710.
Put 5 as the next digit of the answer. 
Result so far: 11245.0
Deduct 4020 from 4730 and we're left with 710.
Include the next digit (9) from the dividend after 710, then repeat: 7109 / 804

On to step 8:
804 can be fit into 7109 8 times, resulting in a remainder of 677.
The next digit of our result is 8. 
Result so far: 112458.0
The remainder is 677 after subtracting 6432 from 7109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Advancing to step 9:
When dividing 6770 by 804, we get 8 with a remainder of 338.
Write down 8 as next digit of the result. 
Result so far: 112458.8
Subtract 6432 from 6770 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 10:
804 goes into 3380 4 times with a remainder of 164.
The next digit of our result is 4. 
Result so far: 112458.84
If we subtract 3216 from 3380, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 11:
1640 divided by 804 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 112458.842
Deduct 1608 from 1640 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
320 divided by 804 is 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 112458.842
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 13:
The number 804 fits into 3200 3 times, leaving a remainder of 788.
The number 3 becomes the next digit in our result. 
Result so far: 112458.84203
If we take 2412 away from 3200, we end up with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Moving on to step 14:
804 can be fit into 7880 9 times, resulting in a remainder of 644.
Put 9 as the next digit of the answer. 
Result so far: 112458.842039
Subtract 7236 from 7880 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.

Going ahead to step 15:
The number 804 fits into 6440 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 112458.8420398
If we take 6432 away from 6440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 16:
80 divided by 804 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 112458.8420398
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 112458.8420398 with a remainder of 8e-08.
