We look at the division of 99765 by 77 
Our goal is to divide 99765 by 77.

On to step 1:
The number 77 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 77

On to step 2:
77 goes into 99 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 77 from 99 leaves us with 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 77

Let's proceed to step 3:
77 can be fit into 227 2 times, resulting in a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 73 after subtracting 154 from 227.
Include the next digit (6) from the dividend after 73, then repeat: 736 / 77

Step 4:
77 can be fit into 736 9 times, resulting in a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Subtract 693 from 736 to get 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 77

Let's proceed to step 5:
77 goes into 435 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1295.0
The remainder is 50 after subtracting 385 from 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 6:
77 can be fit into 500 6 times, resulting in a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 1295.6
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
77 can be fit into 380 4 times, resulting in a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 1295.64
Subtract 308 from 380 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
77 goes into 720 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 1295.649
Deduct 693 from 720 and we're left 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.

Let's proceed to step 9:
If we divide 270 by 77, we get 3 and a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 1295.6493
Subtracting 231 from 270 leaves us 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.

Going ahead to step 10:
77 goes into 390 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1295.64935
Subtract 385 from 390 to 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.

Going ahead to step 11:
77 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 1295.64935
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
77 goes into 500 6 times with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 1295.6493506
The remainder is 38 after subtracting 462 from 500.
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 13:
When dividing 380 by 77, we get 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 1295.64935064
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.

The final result is 1295.64935064 with a remainder of 7.2e-08.
