Let's divide 399254 by 26
We want to figure out the number of times 399254 can be divided by 26.

Step 1:
26 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 26

Moving on to step 2:
26 can be fit into 39 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 13 after subtracting 26 from 39.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 26

On to step 3:
The number 26 fits into 139 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 9 after subtracting 130 from 139.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 26

Step 4:
When dividing 92 by 26, we get 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Deduct 78 from 92 and we're left with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 26

Moving on to step 5:
When dividing 145 by 26, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1535.0
Subtracting 130 from 145 leaves us with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 26

Going ahead to step 6:
154 divided by 26 is 5 with a remainder of 24.
The next digit of our result is 5. 
Result so far: 15355.0
Deduct 130 from 154 and we're left 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:
26 goes into 240 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 15355.9
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.

Moving on to step 8:
If we divide 60 by 26, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 15355.92
Subtract 52 from 60 to 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.

Advancing to step 9:
26 can be fit into 80 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 15355.923
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
26 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 15355.923
If we take 0 away from 20, we end up 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:
The number 26 fits into 200 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 15355.92307
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.

Moving on to step 12:
If we divide 180 by 26, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 15355.923076
Deduct 156 from 180 and we're left 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 13:
When dividing 240 by 26, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 15355.9230769
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
When dividing 60 by 26, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 15355.92307692
Deduct 52 from 60 and we're left 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 final outcome is 15355.92307692, with a leftover of 8e-09.
