65147961 ÷ 804 
Let's see how many times 804 fits into 65147961.

Step 1:
If we divide 6 by 804, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 804

Let's proceed to step 2:
If we divide 65 by 804, we get 0 and a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Take the next digit (1) from the dividend and append it to 65, then repeat: 651 / 804

Going ahead to step 3:
804 goes into 651 0 times with a remainder of 651.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 651, we get 651.
Include the next digit (4) from the dividend after 651, then repeat: 6514 / 804

Moving on to step 4:
If we divide 6514 by 804, we get 8 and a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 6432 from 6514 and we're left with 82.
Bring next digit (7) of the dividend behind the 82 and repeat the process: 827 / 804

Advancing to step 5:
804 goes into 827 1 times with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtracting 804 from 827 leaves us with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 804

Advancing to step 6:
239 divided by 804 is 0 with a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 810.0
The remainder is 239 after subtracting 0 from 239.
Append the next digit (6) from the dividend to 239 and continue with: 2396 / 804

On to step 7:
The number 804 fits into 2396 2 times, leaving a remainder of 788.
The next digit of our result is 2. 
Result so far: 8102.0
Subtract 1608 from 2396 to get 788.
Bring next digit (1) of the dividend behind the 788 and repeat the process: 7881 / 804

Moving on to step 8:
If we divide 7881 by 804, we get 9 and a remainder of 645.
Record the quotient 9 as the next digit in the result. 
Result so far: 81029.0
If we subtract 7236 from 7881, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Moving on to step 9:
804 can be fit into 6450 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 81029.8
If we take 6432 away from 6450, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
804 goes into 180 0 times with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 81029.8
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
804 can be fit into 1800 2 times, resulting in a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 81029.802
The remainder is 192 after subtracting 1608 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 12:
804 can be fit into 1920 2 times, resulting in a remainder of 312.
Use 2 as the next digit of our solution. 
Result so far: 81029.8022
Subtracting 1608 from 1920 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 81029.8022 with a remainder of 0.00312.
