Let's divide 804864 by 77
We want to figure out the number of times 804864 can be divided by 77.

Advancing to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 77

Moving on to step 2:
80 divided by 77 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 3 after subtracting 77 from 80.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 77

Step 3:
34 divided by 77 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 34, we end up with 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 77

Let's proceed to step 4:
If we divide 348 by 77, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 104.0
The remainder is 40 after subtracting 308 from 348.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 77

Moving on to step 5:
When dividing 406 by 77, we get 5 with a remainder of 21.
The next digit of our result is 5. 
Result so far: 1045.0
Deduct 385 from 406 and we're left with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 77

On to step 6:
77 can be fit into 214 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 10452.0
Deduct 154 from 214 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
600 divided by 77 is 7 with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 10452.7
If we take 539 away from 600, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 8:
77 can be fit into 610 7 times, resulting in a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 10452.77
If we take 539 away from 610, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 10452.77 and a remainder of 0.071.
