99989986 ÷ 77 
Let's see how many times 77 fits into 99989986.

Advancing to step 1:
When dividing 9 by 77, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 77

On to step 2:
77 goes into 99 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 77 from 99, we get 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 77

Let's proceed to step 3:
When dividing 229 by 77, we get 2 with a remainder of 75.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 75 after subtracting 154 from 229.
Fetch the next digit (8) from the dividend, attach it to 75 and continue: 758 / 77

Going ahead to step 4:
77 goes into 758 9 times with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
If we take 693 away from 758, we end up with 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 77

Let's proceed to step 5:
659 divided by 77 is 8 with a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 1298.0
If we subtract 616 from 659, we get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 77

On to step 6:
77 can be fit into 439 5 times, resulting in a remainder of 54.
The next digit of our result is 5. 
Result so far: 12985.0
The remainder is 54 after subtracting 385 from 439.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 77

Let's proceed to step 7:
548 divided by 77 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 129857.0
Deduct 539 from 548 and we're left with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 77

On to step 8:
77 goes into 96 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1298571.0
If we subtract 77 from 96, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
77 goes into 190 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 1298571.2
If we take 154 away from 190, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
77 goes into 360 4 times with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 1298571.24
If we take 308 away from 360, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
77 goes into 520 6 times with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 1298571.246
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
580 divided by 77 is 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 1298571.2467
If we subtract 539 from 580, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 13:
The number 77 fits into 410 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1298571.24675
Subtracting 385 from 410 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
77 can be fit into 250 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 1298571.246753
Subtracting 231 from 250 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 15:
77 can be fit into 190 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 1298571.2467532
If we take 154 away from 190, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 16:
If we divide 360 by 77, we get 4 and a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 1298571.24675324
The remainder is 52 after subtracting 308 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 1298571.24675324, and the remainder is 5.2e-08.
