We divide 78651 by 39
Our goal is to divide 78651 by 39.

Let's proceed to step 1:
7 divided by 39 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 39

Step 2:
If we divide 78 by 39, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 78 from 78 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 39

On to step 3:
The number 39 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 6, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 39

Moving on to step 4:
65 divided by 39 is 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 201.0
Deduct 39 from 65 and we're left with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 39

Advancing to step 5:
If we divide 261 by 39, we get 6 and a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 2016.0
Deduct 234 from 261 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 6:
When dividing 270 by 39, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 2016.6
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 2016.69
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
When dividing 90 by 39, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2016.692
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 39, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 2016.6923
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
If we divide 30 by 39, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2016.6923
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
When dividing 300 by 39, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 2016.692307
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
If we divide 270 by 39, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 2016.6923076
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
39 goes into 360 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 2016.69230769
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 2016.69230769 and a remainder of 9e-09.
