We're dividing 981840 by 77 
We want to divide 981840 by 77.

Let's proceed to step 1:
If we divide 9 by 77, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 77

On to step 2:
If we divide 98 by 77, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 21 after subtracting 77 from 98.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 77

On to step 3:
77 can be fit into 211 2 times, resulting in a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 154 from 211 to get 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 77

Moving on to step 4:
77 goes into 578 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 539 from 578, we get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 77

On to step 5:
The number 77 fits into 394 5 times, leaving a remainder of 9.
The next digit of our result is 5. 
Result so far: 1275.0
The remainder is 9 after subtracting 385 from 394.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 77

Moving on to step 6:
77 goes into 90 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 12751.0
Deduct 77 from 90 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
If we divide 130 by 77, we get 1 and a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 12751.1
Subtract 77 from 130 to get 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 8:
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: 12751.16
Subtract 462 from 530 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
If we divide 680 by 77, we get 8 and a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 12751.168
If we subtract 616 from 680, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
640 divided by 77 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 12751.1688
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.

Our division results in 12751.1688 with a remaining 0.00024.
