We look at the division of 843742 by 77 
Our goal is to divide 843742 by 77.

Let's proceed to step 1:
77 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 77

Advancing to step 2:
If we divide 84 by 77, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 7 after subtracting 77 from 84.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 77

Advancing to step 3:
If we divide 73 by 77, we get 0 and a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 73 to get 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 77

Advancing to step 4:
The number 77 fits into 737 9 times, leaving a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
Deduct 693 from 737 and we're left with 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 77

Moving on to step 5:
If we divide 444 by 77, we get 5 and a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 1095.0
Deduct 385 from 444 and we're left with 59.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 77

Step 6:
592 divided by 77 is 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 10957.0
Deduct 539 from 592 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
If we divide 530 by 77, we get 6 and a remainder of 68.
The next digit of our result is 6. 
Result so far: 10957.6
Subtracting 462 from 530 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 8:
When dividing 680 by 77, we get 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 10957.68
Deduct 616 from 680 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
640 divided by 77 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 10957.688
Deduct 616 from 640 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 10957.688, and the remainder is 0.0024.
