We're dividing 86502 by 77 
Let's see how many times 77 fits into 86502.

Going ahead to step 1:
8 divided by 77 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 77

Let's proceed to step 2:
86 divided by 77 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 77 from 86 to get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 77

Step 3:
77 goes into 95 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 18 after subtracting 77 from 95.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 77

Let's proceed to step 4:
77 goes into 180 2 times with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we take 154 away from 180, we end up with 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 77

Step 5:
The number 77 fits into 262 3 times, leaving a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 1123.0
Subtract 231 from 262 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 6:
77 can be fit into 310 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1123.4
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
77 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1123.4
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.

Moving on to step 8:
If we divide 200 by 77, we get 2 and a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 1123.402
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:
The number 77 fits into 460 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 1123.4025
Subtract 385 from 460 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
If we divide 750 by 77, we get 9 and a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 1123.40259
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 11:
The number 77 fits into 570 7 times, leaving a remainder of 31.
The next digit of our result is 7. 
Result so far: 1123.402597
Subtracting 539 from 570 leaves us 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:
When dividing 310 by 77, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1123.4025974
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.

Step 13:
77 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 1123.4025974
The remainder is 20 after subtracting 0 from 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 outcome is 1123.4025974, with a leftover of 2e-08.
