Let's divide 545561 by 77
Let's see how many times 77 fits into 545561.

On to step 1:
The number 77 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 77

Step 2:
If we divide 54 by 77, we get 0 and a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 77

Moving on to step 3:
77 goes into 545 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 539 from 545 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 77

Step 4:
77 goes into 65 0 times with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we subtract 0 from 65, we get 65.
Append the next digit (6) from the dividend to 65 and continue with: 656 / 77

Advancing to step 5:
The number 77 fits into 656 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 708.0
If we take 616 away from 656, we end up with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 77

On to step 6:
If we divide 401 by 77, we get 5 and a remainder of 16.
The next digit of our result is 5. 
Result so far: 7085.0
The remainder is 16 after subtracting 385 from 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
77 goes into 160 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 7085.2
If we subtract 154 from 160, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
The number 77 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 7085.2
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
If we divide 600 by 77, we get 7 and a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 7085.207
Subtracting 539 from 600 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 10:
610 divided by 77 is 7 with a remainder of 71.
The next digit of our result is 7. 
Result so far: 7085.2077
Subtracting 539 from 610 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 7085.2077 and a remainder of 0.00071.
