398250 ÷ 26 
Our goal is to divide 398250 by 26.

Step 1:
If we divide 3 by 26, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 26

Going ahead to step 2:
26 goes into 39 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 26 away from 39, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 26

Step 3:
138 divided by 26 is 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 130 away from 138, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 26

Step 4:
26 goes into 82 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Subtracting 78 from 82 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 26

Step 5:
26 goes into 45 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1531.0
Subtract 26 from 45 to get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 26

On to step 6:
When dividing 190 by 26, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 15317.0
If we take 182 away from 190, we end up 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.

Let's proceed to step 7:
26 can be fit into 80 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 15317.3
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.

Advancing to step 8:
When dividing 20 by 26, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 15317.3
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
26 goes into 200 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 15317.307
Subtracting 182 from 200 leaves us 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.

Step 10:
The number 26 fits into 180 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 15317.3076
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.

Step 11:
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: 15317.30769
If we take 234 away from 240, we end up 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 12:
If we divide 60 by 26, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 15317.307692
The remainder is 8 after subtracting 52 from 60.
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 13:
26 goes into 80 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 15317.3076923
Deduct 78 from 80 and we're left with 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 14:
20 divided by 26 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 15317.3076923
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.

Our division results in 15317.3076923 with a remaining 2e-08.
