843424 divided by 77 
Let's see how many times 77 fits into 843424.

Going ahead to step 1:
8 divided by 77 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 77

Step 2:
84 divided by 77 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 84 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 77

Advancing to step 3:
77 can be fit into 73 0 times, resulting in a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 73 leaves us with 73.
Include the next digit (4) from the dividend after 73, then repeat: 734 / 77

Going ahead to step 4:
When dividing 734 by 77, we get 9 with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
The remainder is 41 after subtracting 693 from 734.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 77

Let's proceed to step 5:
77 goes into 412 5 times with a remainder of 27.
The next digit of our result is 5. 
Result so far: 1095.0
If we take 385 away from 412, we end up with 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 77

Going ahead to step 6:
77 can be fit into 274 3 times, resulting in a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 10953.0
The remainder is 43 after subtracting 231 from 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
77 can be fit into 430 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 10953.5
If we subtract 385 from 430, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
When dividing 450 by 77, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 10953.55
Subtract 385 from 450 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 10953.55, and the remainder is 0.065.
