821344 divided by 77 
Our goal is to divide 821344 by 77.

Going ahead to step 1:
77 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 77

Moving on to step 2:
77 goes into 82 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 5 after subtracting 77 from 82.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 77

Going ahead to step 3:
77 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 51, we get 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 77

Advancing to step 4:
When dividing 513 by 77, we get 6 with a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 106.0
If we subtract 462 from 513, we get 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 77

Advancing to step 5:
77 can be fit into 514 6 times, resulting in a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 1066.0
If we take 462 away from 514, we end up with 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 77

Let's proceed to step 6:
The number 77 fits into 524 6 times, leaving a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 10666.0
Subtract 462 from 524 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
620 divided by 77 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10666.8
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
77 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10666.8
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
77 goes into 400 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 10666.805
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
77 goes into 150 1 times with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 10666.8051
Subtracting 77 from 150 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 11:
77 goes into 730 9 times with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 10666.80519
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
77 can be fit into 370 4 times, resulting in a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 10666.805194
Subtract 308 from 370 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
77 goes into 620 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10666.8051948
Subtract 616 from 620 to 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.

Step 14:
When dividing 40 by 77, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10666.8051948
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 10666.8051948, and the remainder is 4e-08.
