78288837 divided by 39 
Our goal is to divide 78288837 by 39.

Let's proceed to step 1:
The number 39 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 39

Going ahead to step 2:
39 can be fit into 78 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 78 away from 78, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 39

Step 3:
When dividing 2 by 39, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 39

Step 4:
If we divide 28 by 39, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 39

Step 5:
The number 39 fits into 288 7 times, leaving a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 2007.0
Deduct 273 from 288 and we're left with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 39

Moving on to step 6:
When dividing 158 by 39, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 20074.0
Subtract 156 from 158 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 39

Going ahead to step 7:
The number 39 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 200740.0
Subtracting 0 from 23 leaves us with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 39

Moving on to step 8:
237 divided by 39 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 2007406.0
The remainder is 3 after subtracting 234 from 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2007406.0
Deduct 0 from 30 and we're left 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.

Step 10:
39 can be fit into 300 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 2007406.07
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
If we divide 270 by 39, we get 6 and a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 2007406.076
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
39 goes into 360 9 times with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 2007406.0769
If we take 351 away from 360, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
39 goes into 90 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2007406.07692
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.

Advancing to step 14:
39 can be fit into 120 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 2007406.076923
Subtracting 117 from 120 leaves us with 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 15:
39 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2007406.076923
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 2007406.07692307
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 2007406.07692307 with a remaining 2.7e-08.
