We look at the division of 317715 by 78 
Let's see how many times 78 fits into 317715.

Moving on to step 1:
3 divided by 78 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 78

Advancing to step 2:
78 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 78

On to step 3:
78 goes into 317 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 312 from 317 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 78

Advancing to step 4:
When dividing 57 by 78, we get 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 57 leaves us with 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 78

Advancing to step 5:
When dividing 571 by 78, we get 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 407.0
If we take 546 away from 571, we end up with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 78

Going ahead to step 6:
When dividing 255 by 78, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 4073.0
Subtract 234 from 255 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
When dividing 210 by 78, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 4073.2
Deduct 156 from 210 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
If we divide 540 by 78, we get 6 and a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 4073.26
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 4073.269
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
The number 78 fits into 180 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 4073.2692
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 4073.26923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 4073.26923
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
The number 78 fits into 600 7 times, leaving a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 4073.2692307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
540 divided by 78 is 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 4073.26923076
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 4073.26923076 with a remaining 7.2e-08.
