Let's divide 40353 by 78
Let's see how many times 78 fits into 40353.

On to step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 78

Let's proceed to step 2:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 78

Let's proceed to step 3:
When dividing 403 by 78, we get 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 390 from 403 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 78

On to step 4:
If we divide 135 by 78, we get 1 and a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtract 78 from 135 to get 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 78

On to step 5:
573 divided by 78 is 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 517.0
Subtract 546 from 573 to 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.

Step 6:
If we divide 270 by 78, we get 3 and a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 517.3
If we take 234 away from 270, we end up 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.

On to step 7:
78 goes into 360 4 times with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 517.34
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.

Going ahead to step 8:
480 divided by 78 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 517.346
Deduct 468 from 480 and we're left 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.

Step 9:
78 goes into 120 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 517.3461
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.

Advancing to step 10:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 517.34615
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.

Advancing to step 11:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 517.346153
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.

On to step 12:
660 divided by 78 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 517.3461538
If we take 624 away from 660, we end up 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 13:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 517.34615384
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.

The quotient of the division is 517.34615384, and the remainder is 4.8e-08.
