We look at the division of 989984 by 77 
We want to divide 989984 by 77.

On to step 1:
The number 77 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 77

Going ahead to step 2:
98 divided by 77 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 77 from 98, we get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 77

On to step 3:
If we divide 219 by 77, we get 2 and a remainder of 65.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 154 from 219 and we're left with 65.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 77

On to step 4:
If we divide 659 by 77, we get 8 and a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
If we take 616 away from 659, we end up with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 77

Step 5:
77 goes into 438 5 times with a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 1285.0
Subtract 385 from 438 to get 53.
Include the next digit (4) from the dividend after 53, then repeat: 534 / 77

Step 6:
77 goes into 534 6 times with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 12856.0
The remainder is 72 after subtracting 462 from 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
720 divided by 77 is 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 12856.9
If we take 693 away from 720, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 8:
77 goes into 270 3 times with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 12856.93
If we take 231 away from 270, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
When dividing 390 by 77, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12856.935
If we subtract 385 from 390, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
If we divide 50 by 77, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 12856.935
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
77 goes into 500 6 times with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 12856.93506
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
If we divide 380 by 77, we get 4 and a remainder of 72.
The next digit of our result is 4. 
Result so far: 12856.935064
Deduct 308 from 380 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 13:
77 can be fit into 720 9 times, resulting in a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 12856.9350649
Subtract 693 from 720 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 14:
77 can be fit into 270 3 times, resulting in a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 12856.93506493
If we take 231 away from 270, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 12856.93506493, and the remainder is 3.9e-08.
