We're dividing 320311 by 78 
Our goal is to divide 320311 by 78.

Step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 78

Moving on to step 2:
32 divided by 78 is 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 78

Going ahead to step 3:
When dividing 320 by 78, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 312 from 320 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 78

Advancing to step 4:
The number 78 fits into 83 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
The remainder is 5 after subtracting 78 from 83.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 78

Let's proceed to step 5:
51 divided by 78 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 410.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 78

On to step 6:
The number 78 fits into 511 6 times, leaving a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 4106.0
Deduct 468 from 511 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
430 divided by 78 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 4106.5
Deduct 390 from 430 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 78 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 4106.55
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 4106.55, and the remainder is 0.01.
