Let's divide 231597 by 78
We're looking to find how many times 78 goes into 231597.

Moving on to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 78

Going ahead to step 2:
The number 78 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 78

Let's proceed to step 3:
When dividing 231 by 78, we get 2 with a remainder of 75.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 156 away from 231, we end up with 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 78

Step 4:
755 divided by 78 is 9 with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 702 from 755 and we're left with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 78

Going ahead to step 5:
539 divided by 78 is 6 with a remainder of 71.
Write down 6 as next digit of the result. 
Result so far: 296.0
If we take 468 away from 539, we end up with 71.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 78

Step 6:
78 can be fit into 717 9 times, resulting in a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 2969.0
The remainder is 15 after subtracting 702 from 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
78 goes into 150 1 times with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 2969.1
The remainder is 72 after subtracting 78 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 8:
When dividing 720 by 78, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 2969.19
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
180 divided by 78 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2969.192
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.

Going ahead to step 10:
If we divide 240 by 78, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 2969.1923
If we subtract 234 from 240, we 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.

Going ahead to step 11:
If we divide 60 by 78, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 2969.1923
Subtracting 0 from 60 leaves us 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.

Going ahead to step 12:
When dividing 600 by 78, we get 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 2969.192307
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.

On to step 13:
78 goes into 540 6 times with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 2969.1923076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 2969.19230769
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 2969.19230769 with a remainder of 1.8e-08.
