We're dividing 209593 by 78 
Our goal is to divide 209593 by 78.

Moving on to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 78

Let's proceed to step 2:
20 divided by 78 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 78

Advancing to step 3:
78 goes into 209 2 times with a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 53 after subtracting 156 from 209.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 78

On to step 4:
When dividing 535 by 78, we get 6 with a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 468 from 535 to get 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 78

Advancing to step 5:
If we divide 679 by 78, we get 8 and a remainder of 55.
Put 8 as the next digit of the answer. 
Result so far: 268.0
Deduct 624 from 679 and we're left with 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 78

Step 6:
553 divided by 78 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 2687.0
Subtract 546 from 553 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 78, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 2687.0
If we take 0 away from 70, we end up with 70.
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 8:
700 divided by 78 is 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 2687.08
Deduct 624 from 700 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
When dividing 760 by 78, we get 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 2687.089
If we subtract 702 from 760, 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 10:
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: 2687.0897
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
78 goes into 340 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 2687.08974
The remainder is 28 after subtracting 312 from 340.
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 12:
When dividing 280 by 78, we get 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 2687.089743
If we take 234 away from 280, we end up 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 13:
If we divide 460 by 78, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 2687.0897435
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
When dividing 700 by 78, we get 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 2687.08974358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 2687.08974358 and a remainder of 7.6e-08.
