843813 ÷ 77 
Let's see how many times 77 fits into 843813.

Going ahead to step 1:
The number 77 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 77

Advancing to step 2:
77 can be fit into 84 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 77 from 84 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 77

Step 3:
73 divided by 77 is 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 73 and we're left with 73.
Take the next digit (8) from the dividend and append it to 73, then repeat: 738 / 77

Step 4:
The number 77 fits into 738 9 times, leaving a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 693 from 738, we get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 77

Step 5:
If we divide 451 by 77, we get 5 and a remainder of 66.
Write down 5 as next digit of the result. 
Result so far: 1095.0
Subtract 385 from 451 to get 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 77

Moving on to step 6:
When dividing 663 by 77, we get 8 with a remainder of 47.
The next digit of our result is 8. 
Result so far: 10958.0
The remainder is 47 after subtracting 616 from 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
77 can be fit into 470 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10958.6
Subtract 462 from 470 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 77, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 10958.61
Subtract 77 from 80 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
77 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10958.61
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
77 can be fit into 300 3 times, resulting in a remainder of 69.
The next digit of our result is 3. 
Result so far: 10958.6103
Deduct 231 from 300 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 11:
690 divided by 77 is 8 with a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 10958.61038
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 12:
77 can be fit into 740 9 times, resulting in a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 10958.610389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
When dividing 470 by 77, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10958.6103896
Deduct 462 from 470 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
When dividing 80 by 77, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 10958.61038961
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 10958.61038961 with a remainder of 3e-09.
