57216 ÷ 78 
We want to divide 57216 by 78.

Going ahead to step 1:
5 divided by 78 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 78

Going ahead to step 2:
If we divide 57 by 78, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 78

Advancing to step 3:
If we divide 572 by 78, we get 7 and a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 546 from 572 leaves us with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 78

Advancing to step 4:
261 divided by 78 is 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtracting 234 from 261 leaves us with 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 78

Step 5:
276 divided by 78 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 733.0
Subtract 234 from 276 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 6:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 733.5
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.

Let's proceed to step 7:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 733.53
Deduct 234 from 300 and we're left 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.

Moving on to step 8:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 733.538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 733.5384
The remainder is 48 after subtracting 312 from 360.
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 10:
78 can be fit into 480 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 733.53846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 733.538461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
420 divided by 78 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 733.5384615
If we take 390 away from 420, we end up 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.

On to step 13:
When dividing 300 by 78, we get 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 733.53846153
Subtracting 234 from 300 leaves us 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.

The final result is 733.53846153 with a remainder of 6.6e-08.
