We're dividing 86040 by 77 
We want to divide 86040 by 77.

Going ahead to step 1:
8 divided by 77 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 77

Step 2:
The number 77 fits into 86 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 77 from 86, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 77

Let's proceed to step 3:
77 can be fit into 90 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 77 from 90, we get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 77

Step 4:
When dividing 134 by 77, we get 1 with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
If we subtract 77 from 134, we get 57.
Include the next digit (0) from the dividend after 57, then repeat: 570 / 77

Advancing to step 5:
570 divided by 77 is 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 1117.0
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 6:
When dividing 310 by 77, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 1117.4
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.

Moving on to step 7:
The number 77 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1117.4
Subtracting 0 from 20 leaves us 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.

Let's proceed to step 8:
When dividing 200 by 77, we get 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 1117.402
The remainder is 46 after subtracting 154 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
77 can be fit into 460 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 1117.4025
Deduct 385 from 460 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 10:
The number 77 fits into 750 9 times, leaving a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 1117.40259
The remainder is 57 after subtracting 693 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 11:
77 can be fit into 570 7 times, resulting in a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 1117.402597
Deduct 539 from 570 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 12:
If we divide 310 by 77, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1117.4025974
Subtract 308 from 310 to 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.

Advancing to step 13:
77 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1117.4025974
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.

The final result is 1117.4025974 with a remainder of 2e-08.
