804915 ÷ 77 
Our goal is to divide 804915 by 77.

Let's proceed to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 77

Going ahead to step 2:
When dividing 80 by 77, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 77 from 80 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 77

Going ahead to step 3:
If we divide 34 by 77, we get 0 and 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.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 77

Step 4:
When dividing 349 by 77, we get 4 with a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we subtract 308 from 349, we get 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 77

Going ahead to step 5:
77 goes into 411 5 times with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 1045.0
The remainder is 26 after subtracting 385 from 411.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 77

Let's proceed to step 6:
77 can be fit into 265 3 times, resulting in a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 10453.0
If we take 231 away from 265, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
77 goes into 340 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 10453.4
Deduct 308 from 340 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
If we divide 320 by 77, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 10453.44
If we subtract 308 from 320, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 10453.44 and a remainder of 0.012.
