195591 divided by 78 
Our goal is to divide 195591 by 78.

Let's proceed to step 1:
1 divided by 78 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 78

Let's proceed to step 2:
19 divided by 78 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 78

Let's proceed to step 3:
78 goes into 195 2 times with a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 156 from 195 to get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 78

Going ahead to step 4:
78 goes into 395 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 390 from 395 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 78

Moving on to step 5:
If we divide 59 by 78, we get 0 and a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
Subtracting 0 from 59 leaves us with 59.
Bring next digit (1) of the dividend behind the 59 and repeat the process: 591 / 78

Advancing to step 6:
If we divide 591 by 78, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 2507.0
If we take 546 away from 591, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
When dividing 450 by 78, we get 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 2507.5
Subtracting 390 from 450 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.

Moving on to step 8:
78 can be fit into 600 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 2507.57
Deduct 546 from 600 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.

On to step 9:
78 goes into 540 6 times with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 2507.576
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.

Advancing to step 10:
If we divide 720 by 78, we get 9 and a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 2507.5769
If we take 702 away from 720, we end up 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.

Moving on to step 11:
78 goes into 180 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 2507.57692
If we take 156 away from 180, we end up 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.

On to step 12:
If we divide 240 by 78, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 2507.576923
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.

On to step 13:
78 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 2507.576923
Deduct 0 from 60 and we're left 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.

Moving on to step 14:
When dividing 600 by 78, we get 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 2507.57692307
If we take 546 away from 600, we end up 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.

The final result is 2507.57692307 with a remainder of 5.4e-08.
