64715632 ÷ 804 
Our goal is to divide 64715632 by 804.

Let's proceed to step 1:
6 divided by 804 is 0 with 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

Moving on to step 2:
The number 804 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 804

On to step 3:
If we divide 647 by 804, we get 0 and a remainder of 647.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 647, we get 647.
Grab the next digit (1) from the dividend, add it to 647, then carry on: 6471 / 804

On to step 4:
The number 804 fits into 6471 8 times, leaving a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6432 from 6471 to get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 804

Going ahead to step 5:
If we divide 395 by 804, we get 0 and a remainder of 395.
Write down 0 as next digit of the result. 
Result so far: 80.0
The remainder is 395 after subtracting 0 from 395.
Bring next digit (6) of the dividend behind the 395 and repeat the process: 3956 / 804

Moving on to step 6:
804 goes into 3956 4 times with a remainder of 740.
Record the quotient 4 as the next digit in the result. 
Result so far: 804.0
Subtract 3216 from 3956 to get 740.
Take the next digit (3) from the dividend and append it to 740, then repeat: 7403 / 804

Step 7:
When dividing 7403 by 804, we get 9 with a remainder of 167.
The number 9 becomes the next digit in our result. 
Result so far: 8049.0
Deduct 7236 from 7403 and we're left with 167.
Bring next digit (2) of the dividend behind the 167 and repeat the process: 1672 / 804

Advancing to step 8:
The number 804 fits into 1672 2 times, leaving a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 80492.0
Subtract 1608 from 1672 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
If we divide 640 by 804, we get 0 and a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 80492.0
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 10:
If we divide 6400 by 804, we get 7 and a remainder of 772.
Record the quotient 7 as the next digit in the result. 
Result so far: 80492.07
The remainder is 772 after subtracting 5628 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Step 11:
If we divide 7720 by 804, we get 9 and a remainder of 484.
Put 9 as the next digit of the answer. 
Result so far: 80492.079
The remainder is 484 after subtracting 7236 from 7720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 12:
4840 divided by 804 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 80492.0796
Deduct 4824 from 4840 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
804 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 80492.0796
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
804 goes into 1600 1 times with a remainder of 796.
Use 1 as the next digit of our solution. 
Result so far: 80492.079601
Subtracting 804 from 1600 leaves us with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Advancing to step 15:
The number 804 fits into 7960 9 times, leaving a remainder of 724.
Record the quotient 9 as the next digit in the result. 
Result so far: 80492.0796019
The remainder is 724 after subtracting 7236 from 7960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 16:
804 can be fit into 7240 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 80492.07960199
If we subtract 7236 from 7240, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 80492.07960199 with a remainder of 4e-09.
