Let's divide 77843005 by 539
Our goal is to divide 77843005 by 539.

Advancing to step 1:
If we divide 7 by 539, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 539

Going ahead to step 2:
When dividing 77 by 539, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 539

Step 3:
If we divide 778 by 539, we get 1 and a remainder of 239.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 539 from 778 to get 239.
Grab the next digit (4) from the dividend, add it to 239, then carry on: 2394 / 539

Going ahead to step 4:
2394 divided by 539 is 4 with a remainder of 238.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 2156 from 2394 leaves us with 238.
Grab the next digit (3) from the dividend, add it to 238, then carry on: 2383 / 539

Moving on to step 5:
The number 539 fits into 2383 4 times, leaving a remainder of 227.
The next digit of our result is 4. 
Result so far: 144.0
The remainder is 227 after subtracting 2156 from 2383.
Bring next digit (0) of the dividend behind the 227 and repeat the process: 2270 / 539

Moving on to step 6:
539 can be fit into 2270 4 times, resulting in a remainder of 114.
Write down 4 as next digit of the result. 
Result so far: 1444.0
The remainder is 114 after subtracting 2156 from 2270.
Append the next digit (0) from the dividend to 114 and continue with: 1140 / 539

Advancing to step 7:
The number 539 fits into 1140 2 times, leaving a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 14442.0
Subtracting 1078 from 1140 leaves us with 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 539

Moving on to step 8:
When dividing 625 by 539, we get 1 with a remainder of 86.
Write down 1 as next digit of the result. 
Result so far: 144421.0
If we subtract 539 from 625, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
When dividing 860 by 539, we get 1 with a remainder of 321.
Put 1 as the next digit of the answer. 
Result so far: 144421.1
The remainder is 321 after subtracting 539 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 10:
The number 539 fits into 3210 5 times, leaving a remainder of 515.
Put 5 as the next digit of the answer. 
Result so far: 144421.15
Subtract 2695 from 3210 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 11:
5150 divided by 539 is 9 with a remainder of 299.
The next digit of our result is 9. 
Result so far: 144421.159
The remainder is 299 after subtracting 4851 from 5150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Step 12:
If we divide 2990 by 539, we get 5 and a remainder of 295.
The number 5 becomes the next digit in our result. 
Result so far: 144421.1595
Deduct 2695 from 2990 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 13:
539 can be fit into 2950 5 times, resulting in a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 144421.15955
Subtracting 2695 from 2950 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final result is 144421.15955 with a remainder of 0.000255.
