We look at the division of 288429 by 77 
We want to figure out the number of times 288429 can be divided by 77.

Let's proceed to step 1:
77 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 77

Let's proceed to step 2:
77 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 77

Moving on to step 3:
When dividing 288 by 77, we get 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 231 from 288, we get 57.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 77

Advancing to step 4:
77 goes into 574 7 times with a remainder of 35.
The next digit of our result is 7. 
Result so far: 37.0
Deduct 539 from 574 and we're left with 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 77

Going ahead to step 5:
77 can be fit into 352 4 times, resulting in a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 374.0
Deduct 308 from 352 and we're left with 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 77

Step 6:
The number 77 fits into 449 5 times, leaving a remainder of 64.
The next digit of our result is 5. 
Result so far: 3745.0
Deduct 385 from 449 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 7:
If we divide 640 by 77, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 3745.8
The remainder is 24 after subtracting 616 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
77 goes into 240 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3745.83
Subtracting 231 from 240 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
90 divided by 77 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 3745.831
Subtracting 77 from 90 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
77 goes into 130 1 times with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 3745.8311
If we take 77 away from 130, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Our division results in 3745.8311 with a remaining 0.00053.
