We're dividing 303287 by 78 
Our goal is to divide 303287 by 78.

Step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 78

Advancing to step 2:
If we divide 30 by 78, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 78

Going ahead to step 3:
If we divide 303 by 78, we get 3 and a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 234 from 303 leaves us with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 78

On to step 4:
When dividing 692 by 78, we get 8 with a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we subtract 624 from 692, we get 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 78

Going ahead to step 5:
78 goes into 688 8 times with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 388.0
The remainder is 64 after subtracting 624 from 688.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 78

On to step 6:
78 can be fit into 647 8 times, resulting in a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 3888.0
Subtracting 624 from 647 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
78 can be fit into 230 2 times, resulting in a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 3888.2
Deduct 156 from 230 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
740 divided by 78 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 3888.29
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
78 goes into 380 4 times with a remainder of 68.
The next digit of our result is 4. 
Result so far: 3888.294
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 3888.2948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
If we divide 560 by 78, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 3888.29487
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
When dividing 140 by 78, we get 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 3888.294871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 13:
The number 78 fits into 620 7 times, leaving a remainder of 74.
The next digit of our result is 7. 
Result so far: 3888.2948717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 14:
78 goes into 740 9 times with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 3888.29487179
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 3888.29487179, and the remainder is 3.8e-08.
