548379 ÷ 77 
We want to divide 548379 by 77.

Advancing to step 1:
5 divided by 77 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 77

Going ahead to step 2:
54 divided by 77 is 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 77

Moving on to step 3:
The number 77 fits into 548 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 539 from 548, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 77

Advancing to step 4:
77 goes into 93 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 77 from 93, we get 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 77

Let's proceed to step 5:
167 divided by 77 is 2 with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 712.0
If we take 154 away from 167, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 77

Moving on to step 6:
77 goes into 139 1 times with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 7121.0
Subtract 77 from 139 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
620 divided by 77 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 7121.8
Subtract 616 from 620 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
77 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7121.8
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
When dividing 400 by 77, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7121.805
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
77 goes into 150 1 times with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 7121.8051
The remainder is 73 after subtracting 77 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 11:
The number 77 fits into 730 9 times, leaving a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 7121.80519
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
77 goes into 370 4 times with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 7121.805194
If we take 308 away from 370, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
The number 77 fits into 620 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 7121.8051948
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
77 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7121.8051948
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 7121.8051948 and a remainder of 4e-08.
