115520 ÷ 77 
We want to divide 115520 by 77.

Going ahead to step 1:
If we divide 1 by 77, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 77

On to step 2:
If we divide 11 by 77, we get 0 and a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 77

On to step 3:
77 goes into 115 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 38 after subtracting 77 from 115.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 77

Advancing to step 4:
If we divide 385 by 77, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 385 away from 385, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 77

On to step 5:
The number 77 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 150.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 77

On to step 6:
77 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1500.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
77 goes into 200 2 times with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 1500.2
If we take 154 away from 200, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
The number 77 fits into 460 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 1500.25
The remainder is 75 after subtracting 385 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
The number 77 fits into 750 9 times, leaving a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 1500.259
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
77 goes into 570 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 1500.2597
The remainder is 31 after subtracting 539 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
If we divide 310 by 77, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1500.25974
If we subtract 308 from 310, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
The number 77 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1500.25974
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
77 can be fit into 200 2 times, resulting in a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 1500.2597402
If we take 154 away from 200, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
77 goes into 460 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 1500.25974025
The remainder is 75 after subtracting 385 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 1500.25974025 and a remainder of 7.5e-08.
