478209 ÷ 77 
Our goal is to divide 478209 by 77.

On to step 1:
4 divided by 77 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 77

Advancing to step 2:
77 goes into 47 0 times with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 77

Advancing to step 3:
When dividing 478 by 77, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 462 away from 478, we end up with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 77

Step 4:
77 can be fit into 162 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
The remainder is 8 after subtracting 154 from 162.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 77

Step 5:
When dividing 80 by 77, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 621.0
Subtracting 77 from 80 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 77

Let's proceed to step 6:
If we divide 39 by 77, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 6210.0
The remainder is 39 after subtracting 0 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 77 fits into 390 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6210.5
If we take 385 away from 390, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
The number 77 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 6210.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
77 goes into 500 6 times with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 6210.506
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
380 divided by 77 is 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 6210.5064
Subtract 308 from 380 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
When dividing 720 by 77, we get 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 6210.50649
If we subtract 693 from 720, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
If we divide 270 by 77, we get 3 and a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 6210.506493
If we subtract 231 from 270, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
If we divide 390 by 77, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6210.5064935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
77 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 6210.5064935
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 6210.5064935 and a remainder of 5e-08.
