We divide 129994 by 78
Our goal is to divide 129994 by 78.

On to step 1:
78 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 78

Advancing to step 2:
The number 78 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 78

Step 3:
The number 78 fits into 129 1 times, leaving a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 78 from 129, we get 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 78

Step 4:
If we divide 519 by 78, we get 6 and a remainder of 51.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 468 from 519 and we're left with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 78

Let's proceed to step 5:
519 divided by 78 is 6 with a remainder of 51.
The next digit of our result is 6. 
Result so far: 166.0
Subtracting 468 from 519 leaves us with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 78

Advancing to step 6:
78 goes into 514 6 times with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 1666.0
If we take 468 away from 514, 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.

Step 7:
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: 1666.5
Subtracting 390 from 460 leaves us 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:
When dividing 700 by 78, we get 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 1666.58
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 1666.589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
78 goes into 580 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 1666.5897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
340 divided by 78 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 1666.58974
Subtract 312 from 340 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 12:
280 divided by 78 is 3 with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 1666.589743
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.

Moving on to step 13:
When dividing 460 by 78, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 1666.5897435
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.

Going ahead to step 14:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 1666.58974358
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 1666.58974358 and a remainder of 7.6e-08.
