86402944 divided by 77 
We're looking to find how many times 77 goes into 86402944.

Moving on to step 1:
77 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 77

Step 2:
86 divided by 77 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 77 from 86 leaves us with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 77

Let's proceed to step 3:
The number 77 fits into 94 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 77 from 94 leaves us with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 77

Let's proceed to step 4:
When dividing 170 by 77, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we subtract 154 from 170, we get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 77

Step 5:
162 divided by 77 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 1122.0
If we subtract 154 from 162, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 77

Moving on to step 6:
The number 77 fits into 89 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 11221.0
Subtract 77 from 89 to get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 77

Going ahead to step 7:
77 can be fit into 124 1 times, resulting in a remainder of 47.
The next digit of our result is 1. 
Result so far: 112211.0
Deduct 77 from 124 and we're left with 47.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 77

Step 8:
77 can be fit into 474 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 1122116.0
The remainder is 12 after subtracting 462 from 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
If we divide 120 by 77, we get 1 and a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1122116.1
Subtracting 77 from 120 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 10:
77 can be fit into 430 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 1122116.15
Subtracting 385 from 430 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
The number 77 fits into 450 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 1122116.155
Deduct 385 from 450 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 1122116.155 with a balance of 0.0065.
