We're dividing 570280 by 77 
Let's see how many times 77 fits into 570280.

Advancing to step 1:
77 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 77

On to step 2:
77 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 77

Advancing to step 3:
When dividing 570 by 77, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 31 after subtracting 539 from 570.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 77

On to step 4:
77 goes into 312 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtract 308 from 312 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 77

Step 5:
77 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 740.0
If we take 0 away from 48, we end up with 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 77

Advancing to step 6:
If we divide 480 by 77, we get 6 and a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 7406.0
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 77 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 7406.2
Subtract 154 from 180 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
260 divided by 77 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 7406.23
Subtracting 231 from 260 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
290 divided by 77 is 3 with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 7406.233
The remainder is 59 after subtracting 231 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final result is 7406.233 with a remainder of 0.0059.
