We divide 199987 by 78
We want to divide 199987 by 78.

On to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our 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

Step 2:
If we divide 19 by 78, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 78

Advancing to step 3:
199 divided by 78 is 2 with a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 43 after subtracting 156 from 199.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 78

Let's proceed to step 4:
78 can be fit into 439 5 times, resulting in a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 390 from 439, we get 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 78

Step 5:
498 divided by 78 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 256.0
Subtracting 468 from 498 leaves us with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 78

On to step 6:
The number 78 fits into 307 3 times, leaving a remainder of 73.
The next digit of our result is 3. 
Result so far: 2563.0
The remainder is 73 after subtracting 234 from 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
78 can be fit into 730 9 times, resulting in a remainder of 28.
The next digit of our result is 9. 
Result so far: 2563.9
Subtract 702 from 730 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
If we divide 280 by 78, we get 3 and a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 2563.93
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.

Advancing to step 9:
78 can be fit into 460 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 2563.935
If we subtract 390 from 460, we 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 10:
If we divide 700 by 78, we get 8 and a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 2563.9358
Subtracting 624 from 700 leaves us 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.

Step 11:
78 goes into 760 9 times with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 2563.93589
The remainder is 58 after subtracting 702 from 760.
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 12:
580 divided by 78 is 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 2563.935897
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
78 can be fit into 340 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 2563.9358974
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
78 goes into 280 3 times with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 2563.93589743
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.

Our division results in 2563.93589743 with a remaining 4.6e-08.
