We're dividing 399280 by 26 
We want to figure out the number of times 399280 can be divided by 26.

Advancing to step 1:
The number 26 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 26

Let's proceed to step 2:
39 divided by 26 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 26 from 39 to get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 26

Going ahead to step 3:
26 goes into 139 5 times with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 130 away from 139, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 26

Advancing to step 4:
When dividing 92 by 26, we get 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
If we subtract 78 from 92, we get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 26

Moving on to step 5:
26 can be fit into 148 5 times, resulting in a remainder of 18.
The next digit of our result is 5. 
Result so far: 1535.0
The remainder is 18 after subtracting 130 from 148.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 26

Going ahead to step 6:
The number 26 fits into 180 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 15356.0
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.

Step 7:
The number 26 fits into 240 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 15356.9
If we subtract 234 from 240, we 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.

Advancing to step 8:
26 goes into 60 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 15356.92
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
26 can be fit into 80 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 15356.923
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
If we divide 20 by 26, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 15356.923
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
When dividing 200 by 26, we get 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 15356.92307
Deduct 182 from 200 and we're left 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.

Going ahead to step 12:
The number 26 fits into 180 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 15356.923076
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
When dividing 240 by 26, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 15356.9230769
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.

Let's proceed to step 14:
60 divided by 26 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 15356.92307692
Subtracting 52 from 60 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 15356.92307692, and the remainder is 8e-09.
