539913 ÷ 78 
We want to divide 539913 by 78.

Going ahead to step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 78

Advancing to step 2:
When dividing 53 by 78, we get 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 78

Let's proceed to step 3:
539 divided by 78 is 6 with a remainder of 71.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 468 from 539 and we're left with 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 78

Moving on to step 4:
719 divided by 78 is 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtracting 702 from 719 leaves us with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 78

Step 5:
If we divide 171 by 78, we get 2 and a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 692.0
Deduct 156 from 171 and we're left with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 78

On to step 6:
The number 78 fits into 153 1 times, leaving a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 6921.0
Deduct 78 from 153 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
If we divide 750 by 78, we get 9 and a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 6921.9
Deduct 702 from 750 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
The number 78 fits into 480 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 6921.96
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
120 divided by 78 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 6921.961
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
If we divide 420 by 78, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 6921.9615
Deduct 390 from 420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
When dividing 300 by 78, we get 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 6921.96153
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
660 divided by 78 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 6921.961538
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
78 goes into 360 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 6921.9615384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 6921.96153846
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 6921.96153846 with a remainder of 1.2e-08.
