53063058 ÷ 804 
Let's see how many times 804 fits into 53063058.

Step 1:
When dividing 5 by 804, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 804

Going ahead to step 2:
The number 804 fits into 53 0 times, leaving a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 804

Advancing to step 3:
When dividing 530 by 804, we get 0 with a remainder of 530.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 530 after subtracting 0 from 530.
Fetch the next digit (6) from the dividend, attach it to 530 and continue: 5306 / 804

Step 4:
If we divide 5306 by 804, we get 6 and a remainder of 482.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 4824 from 5306 to get 482.
Bring next digit (3) of the dividend behind the 482 and repeat the process: 4823 / 804

Step 5:
When dividing 4823 by 804, we get 5 with a remainder of 803.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 4020 from 4823 to get 803.
Bring next digit (0) of the dividend behind the 803 and repeat the process: 8030 / 804

Moving on to step 6:
The number 804 fits into 8030 9 times, leaving a remainder of 794.
Put 9 as the next digit of the answer. 
Result so far: 659.0
If we subtract 7236 from 8030, we get 794.
Take the next digit (5) from the dividend and append it to 794, then repeat: 7945 / 804

Advancing to step 7:
When dividing 7945 by 804, we get 9 with a remainder of 709.
Put 9 as the next digit of the answer. 
Result so far: 6599.0
If we take 7236 away from 7945, we end up with 709.
Bring next digit (8) of the dividend behind the 709 and repeat the process: 7098 / 804

Moving on to step 8:
7098 divided by 804 is 8 with a remainder of 666.
Use 8 as the next digit of our solution. 
Result so far: 65998.0
The remainder is 666 after subtracting 6432 from 7098.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Let's proceed to step 9:
804 goes into 6660 8 times with a remainder of 228.
The number 8 becomes the next digit in our result. 
Result so far: 65998.8
Subtracting 6432 from 6660 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 10:
If we divide 2280 by 804, we get 2 and a remainder of 672.
The next digit of our result is 2. 
Result so far: 65998.82
If we take 1608 away from 2280, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 11:
If we divide 6720 by 804, we get 8 and a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 65998.828
If we subtract 6432 from 6720, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 12:
The number 804 fits into 2880 3 times, leaving a remainder of 468.
Use 3 as the next digit of our solution. 
Result so far: 65998.8283
Subtracting 2412 from 2880 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 13:
4680 divided by 804 is 5 with a remainder of 660.
Write down 5 as next digit of the result. 
Result so far: 65998.82835
Deduct 4020 from 4680 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 14:
804 goes into 6600 8 times with a remainder of 168.
Use 8 as the next digit of our solution. 
Result so far: 65998.828358
Subtract 6432 from 6600 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 15:
804 can be fit into 1680 2 times, resulting in a remainder of 72.
The next digit of our result is 2. 
Result so far: 65998.8283582
If we subtract 1608 from 1680, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 16:
The number 804 fits into 720 0 times, leaving a remainder of 720.
Put 0 as the next digit of the answer. 
Result so far: 65998.8283582
Deduct 0 from 720 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

The final outcome is 65998.8283582, with a leftover of 7.2e-07.
