64905857 ÷ 804 
We want to divide 64905857 by 804.

Step 1:
If we divide 6 by 804, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 804

Let's proceed to step 2:
If we divide 64 by 804, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 804

Moving on to step 3:
When dividing 649 by 804, we get 0 with a remainder of 649.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 649 to get 649.
Grab the next digit (0) from the dividend, add it to 649, then carry on: 6490 / 804

On to step 4:
6490 divided by 804 is 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 6432 from 6490, we get 58.
Fetch the next digit (5) from the dividend, attach it to 58 and continue: 585 / 804

On to step 5:
The number 804 fits into 585 0 times, leaving a remainder of 585.
The next digit of our result is 0. 
Result so far: 80.0
If we take 0 away from 585, we end up with 585.
Fetch the next digit (8) from the dividend, attach it to 585 and continue: 5858 / 804

Moving on to step 6:
804 goes into 5858 7 times with a remainder of 230.
Record the quotient 7 as the next digit in the result. 
Result so far: 807.0
Subtracting 5628 from 5858 leaves us with 230.
Bring next digit (5) of the dividend behind the 230 and repeat the process: 2305 / 804

Moving on to step 7:
804 can be fit into 2305 2 times, resulting in a remainder of 697.
The number 2 becomes the next digit in our result. 
Result so far: 8072.0
If we take 1608 away from 2305, we end up with 697.
Grab the next digit (7) from the dividend, add it to 697, then carry on: 6977 / 804

On to step 8:
If we divide 6977 by 804, we get 8 and a remainder of 545.
Write down 8 as next digit of the result. 
Result so far: 80728.0
Subtracting 6432 from 6977 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 9:
If we divide 5450 by 804, we get 6 and a remainder of 626.
The next digit of our result is 6. 
Result so far: 80728.6
If we take 4824 away from 5450, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 10:
804 goes into 6260 7 times with a remainder of 632.
Write down 7 as next digit of the result. 
Result so far: 80728.67
If we take 5628 away from 6260, we end up with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 11:
When dividing 6320 by 804, we get 7 with a remainder of 692.
Use 7 as the next digit of our solution. 
Result so far: 80728.677
The remainder is 692 after subtracting 5628 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

In conclusion, the division gives 80728.677 with a balance of 0.0692.
