We're dividing 549869 by 77 
We're looking to find how many times 77 goes into 549869.

Moving on to step 1:
The number 77 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 77

Advancing to step 2:
54 divided by 77 is 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 77

Advancing to step 3:
If we divide 549 by 77, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 539 from 549, we get 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 77

On to step 4:
If we divide 108 by 77, we get 1 and a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Deduct 77 from 108 and we're left with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 77

On to step 5:
316 divided by 77 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 714.0
Subtracting 308 from 316 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 77

On to step 6:
77 can be fit into 89 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 7141.0
Deduct 77 from 89 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 77 fits into 120 1 times, leaving a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 7141.1
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.

Step 8:
When dividing 430 by 77, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 7141.15
Subtract 385 from 430 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
The number 77 fits into 450 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7141.155
The remainder is 65 after subtracting 385 from 450.
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 7141.155 with a balance of 0.0065.
