Let's divide 315703 by 78
Our goal is to divide 315703 by 78.

Advancing to step 1:
78 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 78

Step 2:
If we divide 31 by 78, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 78

On to step 3:
78 can be fit into 315 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 312 from 315 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 78

Moving on to step 4:
When dividing 37 by 78, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 37, we get 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 78

Step 5:
78 can be fit into 370 4 times, resulting in a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
Subtract 312 from 370 to get 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 78

Going ahead to step 6:
If we divide 583 by 78, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 4047.0
Subtracting 546 from 583 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
When dividing 370 by 78, we get 4 with a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 4047.4
If we subtract 312 from 370, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 4047.47
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
340 divided by 78 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 4047.474
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 4047.4743
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
When dividing 460 by 78, we get 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 4047.47435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
700 divided by 78 is 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 4047.474358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 4047.4743589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 4047.47435897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 4047.47435897 and a remainder of 3.4e-08.
